Abstract
A golf club head includes a frame having a plurality of hollow axial members extending from the front side to the rear side, and a hosel part is integrally formed with the frame. A foam resin core is deposited around the frame. A face plate is disposed at the front side of the frame. A synthetic resin covering is applied over the frame and over the core by installing the assembly of the frame and core in a mold and pouring in the synthetic resin material at a low pressure so as not to deform or shift the frame or the core and the synthetic resin fills the gaps among the frame, the core and the face plate.
