Patent ID: 8348786

Claim:
An iron-type golf club head comprising a main body ( 2 ) having a front surface (FF) including an impact area for striking a ball, a back surface (FB) opposite to the front surface, and an outer circumferential surface (Ph) extending between the front surface and the back surface and including a top surface (TP), a toe surface (TO) and a sole surface (SO), and a hosel ( 3 ) protruding upwardly from the main body on the heel-side of the main body and having a shaft inserting hole ( 3 e ) into which an end of a club shaft is inserted, wherein a major part of the front surface (FF) and a major part of the sole surface (FB) are formed by a metal material having a specific gravity ρ1, a major part of the back surface (FB) and a major part of the top surface (TP) are formed by a fiber reinforced resin having a specific gravity ρ2 lower than the specific gravity ρ1, a lower part of the toe surface (TO) is formed by a metal material having a specific gravity ρ3 higher than the specific gravity ρ1, and the hosel ( 3 ) is made of a metal material having a specific gravity ρ4 higher than the specific gravity ρ1.
