ABSTRACT:
A golf club head of composite material comprises an outer shell, an inner shell, a base plate, and a front wall. The outer shell of a metal material is provided with a receiving space and a neck having therein a shaft hole in communication with the receiving space. The inner shell of a fiber-reinforced resin material is adhered to the inner wall of the receiving space of the outer shell and is provided with a cell facing the open end of the outer shell and with an annular shoulder adjacent to the open end of the outer shell. The base plate is arranged on the annular shoulder of the inner shell so as to seal off the cell of the inner shell and to form a shaping slot located between the base plate and the open end of the outer shell. The front wall of a fiber-reinforced resin material is embedded in the shaping slot to form a ball-striking face of the golf club head.
