Abstract

A head (2) includes an outer shell portion (4) forming an external surface of the head and a hollow portion (16) of the head, an inside extended portion (18) extended from the outer shell portion (4) to an inner part of the head, a housing portion (s1) formed by the outer shell portion (4) and the inside extended portion (18), and an adjusting material (w1) disposed in the housing portion (s1). The outer shell portion (4) is formed by bonding a plurality of outer shell forming members (26) and (28) formed integrally respectively. The outer shell forming member (26) has the inside extended portion (18), and the outer shell forming member (28) has the outer shell portion (4) to be a part of the housing portion (s1). One of the outer shell forming members may have the whole housing portion (s1) and may be formed by casting a metallic material.
