         4 . The head according to  claim 1 , wherein the notched portion is filled with a viscoelastic material. 
     
     
         5 . A putter head comprising a head body and a face insert mounted on a face surface of the head body, wherein
 a notched portion is provided in a rear surface of the face insert to extend downward from an upper end portion.   
     
     
         6 . The head according to  claim 5 , wherein the notched portion extends from a left end of the face insert to a right end thereof. 
     
     
         7 . The head according to  claim 5 , wherein a lower edge portion of the rear surface of the face insert abuts against a bottom wall surface of a recessed portion provided in the face surface, and is fixed on the head body by a screw member. 
     
     
         8 . The head according to  claim 5 , wherein the notched portion is filled with a viscoelastic material. 
     
     
         9 . A putter head comprising a head body and a face insert mounted on a face surface of said head body, wherein
 the face insert comprises   a plate portion disposed on the face surface, and   a bracket portion which is continuous with an upper edge of said plate portion and extends backward along a top surface of the head body,   said bracket portion is fixed on an upper surface portion of the head body, and   a rear surface of said plate portion and the head body are spaced apart from each other.   
     
     
         10 . The head according to  claim 9 , wherein a viscoelastic material is disposed between the rear surface of said plate portion and the head body. 
     
     
         11 . The head according to  claim 9 , wherein
 said bracket portion comprises a bolt insertion hole which vertically runs therethrough, and   a bolt is screwed into the head body via said bolt insertion hole, thereby fixing the face insert on the head body.   
     
     
         12 . The head according to  claim 9 , wherein
 said bracket portion comprises a depending portion which hangs over a rear surface of the head body,   a bolt insertion hole runs through said depending portion in a front-to-back direction, and   a bolt inserted in said bolt insertion hole is screwed into the head body, thereby fixing the face insert on the head body.   
     
     
         13 . The head according to  claim 9 , wherein a groove is provided in a top surface of the head body to engage with said bracket portion. 
     
     
         14 . The head according to  claim 9 , wherein
 the face insert includes a plurality of face inserts including plate portions with different thicknesses as spares, and   one of the face inserts, which is selected from the spares, is detachably mounted on the head body.   
     
     
         15 . The head according to  claim 10 , wherein
 the viscoelastic material includes a plurality of viscoelastic materials with different thicknesses as spares, and   the viscoelastic material with a thickness corresponding to a thickness of the face insert is selected from the spares, and disposed between the rear surface of said plate portion and the head body.
