Abstract
A golf club having a crown of such an improved strength that it can be thin-walled. A head 1 is hollow and metallic. A number of depressions 26 are formed by forging, for example, on nearly an entire area on an outside surface of a crown 1a of the head 1. Thus, the strength of the crown 1a is improved, thus enabling it to be thin-walled. Accordingly, the head 1 can be large-sized, with its center of gravity being lowered.
