Abstract
A golf club head having a club face for hitting a ball comprises a hollow main body provided with a front opening, and a face member disposed at the front of the main body so that a front surface thereof forms at least a major part of the club face, and a rear surface thereof faces a hollow of the main body. The peripheral edge of the face member is welded to the main body so as to form a weld bead, and the width of the weld bead is changed so that a difference (Wmax−Wmin) between the maximum width Wmax and minimum width Wmin is not less than 1 mm.
