ABSTRACT:
In construction of a shell-type wood golf club head, at least its crown is made of a material of a rigidity lower than that of a material forming the other sections of the club head. The crown exhibits upward elastic deformation upon striking a ball and allows the face to incline rearwards, thereby providing a temporarily increased loft which suppresses undesirable back spin of the balls and assures longer shots and smooth run of the balls after landing.
