         6 . The instantaneous heating apparatus of  claim 5 , wherein the external diameter of the pressing force acting member is greater than the internal diameter of the hollow, elliptical or polygonal cylinder formed by coupling the pressing members. 
     
     
         7 . The instantaneous heating apparatus of  claim 3 , wherein the pressing force acting member has a fitting protrusion fitted into a fitting hole formed in the insertion part. 
     
     
         8 . The instantaneous heating apparatus of  claim 1 , wherein the passage forming member is formed of silicon. 
     
     
         9 . The instantaneous heating apparatus of  claim 1 , wherein a passage forming groove forming the heating passage is formed on the outer circumference of the passage forming member. 
     
     
         10 . The instantaneous heating apparatus of  claim 9 , wherein the passage forming groove has a spiral shape. 
     
     
         11 . The instantaneous heating apparatus of  claim 1 , wherein a water inlet passage and a water outlet passage are formed in the water inlet part and the water outlet part, respectively. 
     
     
         12 . The instantaneous heating apparatus of  claim 11 , wherein a portion of the water inlet part and a portion of the water outlet part are inserted in one side and the other side of the insertion part, respectively, formed inside the passage forming member. 
     
     
         13 . The instantaneous heating apparatus of  claim 11 , wherein a first connection hole and a second connection hole, connecting each of the water inlet passage and the water outlet passage to the heating passage, are formed in the one side and the other side of the passage forming member, respectively. 
     
     
         14 . The instantaneous heating apparatus of  claim 11 , wherein the water inlet part or the water outlet part comprises a temperature sensor measuring the temperature of water flowing in the water inlet passage or the water outlet passage. 
     
     
         15 . The instantaneous heating apparatus of  claim 1 , wherein the heating part comprises:
 a heating member having the passage forming member disposed therein; and   a heater attached to the heating member to heat the heating member.   
     
     
         16 . The instantaneous heating apparatus of  claim 15 , wherein the heater is a surface-type heater. 
     
     
         17 . The instantaneous heating apparatus of  claim 1 , further comprising a cover part covering the water inlet part, the heating part and the water outlet part. 
     
     
         18 . The instantaneous heating apparatus of  claim 17 , wherein the cover part comprises:
 a water inlet-side cover member covering the water inlet part and a portion of the heating part; and   a water outlet-side cover member coupled to the water inlet-side cover member to cover the remainder of the heating part and the water outlet part.
