摘要:
A golf club head comprises: a hollow main body made of at least one metal material and provided in at least one of a crown portion and a sole portion of the head with an opening; and an FRP part covering said opening and made of at least one resinous material reinforced with fibers, wherein the fibers include: longitudinal fibers oriented in a direction substantially parallel to the front-back direction of the head; and traversal fibers oriented in a direction substantially perpendicular to the front-back direction, and the longitudinal fibers are less than the traversal fibers with respect to a total weight of fibers in a unit area and/or a total of tensile elastic moduli of fibers in a unit area.
