An iron-type golf club head 1 can elongate a travelling distance of balls for a long iron and can enable the better controlling of balls for a short iron. A head body 8, having a face 3, is formed from one material, while a hosel 7 formed from another material having the different specific gravity than that of the head body 8. For long irons, the material of the hosel 7 is denser than that of the head body 8, while for short irons, the material of the head body 8 is denser than that of the hosel 7. A friction welding process may be used to join the head body 8 to the hosel 7.
