A method used for forming a FRP golf club head comprises a process of inserting a first pin (4), which is for making a neck hole, into a mixture of bubble type fillers and epoxy resin, a process of producing a core body (1) in molds (5,5'), a process of covering glass fiber (2) and carbon fiber (3) over the core body (1) with a second pin (4') inserted into the hole made from the first pin, and a process of heating and pressing molds (7,7',7") with a sole plate (6) fixed at the mold (7). The method provides enhanced repulsive force of the golf club head.
