         2 . The wig according to  claim 1 , wherein said stitch portion fixing of hair is realized by gelation of said adhesive layer,
 a repeated bondability and a peelability of the adhesive layer is realized after completion of gelation reaction of the adhesive layer.   
     
     
         3 . The wig according to  claim 1 , wherein the adhesive layer is made of urethane gel. 
     
     
         4 . The wig according to  claim 3 , wherein the urethane gel made of an urethane resin pressure-sensitive adhesive of a two liquid mixture type comprising a main agent and a solidifying agent, and the main agent being the polyol with urethane resin as a main component, and the solidifying agent with polyisothyanate as a main component. 
     
     
         5 . The wig according to  claim 1 , wherein a surface of the artificial skin is deglossed. 
     
     
         6 . The wig according to  claim 5 , wherein a deglossed surface is formed by mixing a deglossing agent to the artificial skin, and further by forming a fine concave and convex portion on the surface of the artificial skin. 
     
     
         7 . The wig according to  claim 6 , wherein the deglossing agent is composed of inorganic particles. 
     
     
         8 . The wig according to  claim 6 , wherein the fine concave and convex portion is formed by copying with fine meshes. 
     
     
         9 . The wig according to  claim 1 , wherein the front edge of the artificial skin is formed wave-shaped. 
     
     
         10 . The wig according to  claim 1 , wherein a thickness of the artificial skin is in a range of 0.08 mm to 0.12 mm. 
     
     
         11 . A method of manufacturing a wig comprising:
 a first step for preparing an artificial skin to be a front portion by coating and drying a thermoplastic elastomer on a male pattern of a head shape, as well as a net pattern to be a rear portion connected with the artificial skin by making a pattern of a net member similar to a wearer's head shape;   a second step for forming a connecting portion by overlapping the net pattern on upper or lower side of the artificial skin, and sewing or bonding a portion to be a rear edge of the artificial skin and a portion to be a front edge of the net pattern to be connected therewith;   a third step for attaching hair to the artificial skin to be the front portion, the net pattern to be the rear portion and the connecting portion;   a fourth step for forming an adhesive layer on a reverse side of the artificial skin to be the front portion; and   a fifth step for cutting and removing an unnecessary net member at the front portion and an unnecessary artificial skin at the rear portion, respectively.   
     
     
         12 . The method of manufacturing a wig according to  claim 11 , wherein an order of working steps may be arbitrarily changed for the third hair attaching step, the fourth adhesive layer forming step, and the fifth step of cutting and removing the unnecessary parts. 
     
     
         13 . The method of manufacturing a wig according to  claim 11  or  12 , wherein the fourth step is mixing and stirring a solution containing a main agent, a solidifying agent, and an organic solvent, leaving for a predetermined time at room temperature to make a reaction proceed, coating and heating the solution to a reverse side of the artificial skin to bond it to the reverse side of the artificial skin, and cooling after heating to form the adhesive layer on the reverse side of said artificial skin. 
     
     
         14 . The method of manufacturing a wig according to  claim 11 , wherein a surface of the artificial skin is deglossed. 
     
     
         15 . The method of manufacturing a wig according to  claim 14 , wherein the deglossing is conducted by mixing a deglossing agent to the artificial skin, and further forming a fine concave and convex portion on the surface of the artificial skin. 
     
     
         16 . The method of manufacturing a wig according to  claim 15 , wherein the deglossing agent is composed of inorganic particles. 
     
     
         17 . The method of manufacturing a wig according to  claim 15 , wherein the fine concave and convex portion is formed by copying with fine meshes. 
     
     
         18 . The method of manufacturing a wig according to  claim 11 , wherein a front edge of the artificial skin is formed wave-shaped. 
     
     
         19 . The method of manufacturing a wig according to  claim 11 , wherein a thickness of the artificial skin is in a range of 0.08 mm to 0.12 mm. 
     
     
         20 . The method of manufacturing a wig according to  claim 11  or  12 , wherein said fourth step is applying and gelling a mixed solution of polyol and polyisocyanate to the reverse side of said artificial skin to form said adhesive layer on the reverse side of said artificial skin. 
     
     
         21 . The wig according to  claim 1 , wherein said stitch portion of hair is adhered and fixed unpeelably on the reverse side of the artificial skin material.
