A golf club head includes: a head body having a front face and a recess formed in the front face; a striking member fitted in the recess, and having a striking plate flush with the front face and having a thickness ranging from 0.6 mm to 1.4 mm, a carbon-fibre composite layer having a thickness ranging from 3.0 mm to 5.0 mm, and a first adhesive layer for adhering the striking plate to the composite layer; and a second adhesive layer to adhere the composite layer of the striking member to the head body. A weight ratio of the composite layer to the striking member ranges from 50% to 85%.

1 . A golf club head, comprising: 
 a head body including a front face and a recess that is formed in said front face;    a striking member fitted in said recess, and including a striking plate flush with said front face and having a thickness ranging from 0.6 mm to 1.4 mm, a carbon-fibre composite layer backing said striking member and having a thickness ranging from 3.0 mm to 5.0 mm, and a first adhesive layer for adhering said striking plate to said composite layer, a weight ratio of said composite layer to said striking member ranging from 50% to 85%; and    a second adhesive layer to adhere said composite layer of said striking member to said head body.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein said first adhesive layer includes a meshed material and an adhesive applied on said meshed material.
