A method for manufacturing a golf club head with a disparate metallic material provided on a hosel side of the head, which can improve degree of freedom in the design of a head. A head body is made up of a columnar material body 13 made from a forgeable metallic material such as copper and a disparate metallic member 12 as an axial member. The disparate metallic member 12 has its proximal end 12A inserted into a bore 14 formed along a center of axis of the material body 13, while its distal end 12B protruded in the axial direction X. The material body 13 is placed on a lower die 22 which is formed with a mold 21 defining a contour of the head body 11, and then an upper die is pressed thereto. Thus, hot forging process is carried out to form a golf club head.
