Abstract
A golf club head for lowering the center of gravity of a head body. A sole portion of the head body is formed with a concave portion, into which is fitted a denser balance weight of which the specific gravity is greater than that of the head body. The concave portion has a front end located at a face side of the sole portion, while a back end thereof is located backward relative to a center portion of the sole portion, said back portion protruding more backward at its toe side than at its heel side. According to the invention, the center of gravity G of a head body can be drastically lowered and the distance between the center of gravity G and a face can be elongated, thus enlarging so-called a sweet area without weakening a strength of the head body. Further, as the concave portion proturudes more backward at its toe side than its heel side, so-called slicing balls can be prevented.
