Abstract
A golf club head has a hollow structure composed of a head main body including a face portion provided with an opening and a face member fitted in the opening and welded to the head main body. The welded part between the face member and the head main body includes a crown-side welded part positioned substantially at the upper edge or alternatively spaced apart from the upper edge toward the lower edge by a certain distance, and a sole-side welded part spaced apart from the lower edge toward the upper edge by a certain distance which is more than zero and more than the distance. The face portion is provided between the sole-side welded part and the lower edge with a sole-side thin area whose thickness is less than a thickness of the face member.
