Abstract

A golf club head includes a sole of metal material, an inner head member integral with the sole and having a substantially triangular shape in cross section, a hosel for receiving a shaft, and an outer head member formed of carbon fiber reinforced resin material and having a substantially inverted V-shaped cross-sectional configuration covering the entirety of the inner head member. Lower ends of the outer head member are in close contact with shoulders formed between the sole and the lower end of the inner head member, and marginal edges of such lower ends are flush with the sole. The joint between the inner and outer head members is strengthened by elements formed on the outer surface of the inner head member.
