A fiber-reinforced member includes: a base member having a tubular region with an outer circumferential surface extending along and substantially in parallel with an axial direction; and a fiber-reinforced resin layer constituted of a tow prepreg wound in an overlapping manner to cover the outer circumferential surface of the base member along a predetermined direction crossing the axial direction when viewed in a radial direction of the base member, the tow prepreg serving as a widened tape-like member. The tape-like member constituting the fiber-reinforced resin layer has a portion having a fiber line extending along a direction crossing the predetermined direction. A size of a width of the tape-like member constituting the fiber-reinforced resin layer is not less than 100 times and not more than 400 times as large as a size of a thickness of the tape-like member constituting the fiber-reinforced resin layer in the radial direction.

Fiber-reinforced member and method for manufacturing same

The present invention intends to prevent deviation and gap from being generated in a joining section of a golf club in which a head main bodyA and a surface materialB are integrated by joining together and provide a high quality golf club head having an improved durability and manufacturing method thereof. In the golf club head in which the head main bodyA and the surface materialB are joined together such that they are integral, a grooveis provided in a joining section between the both members and joint materialcomposed of fiber reinforced resin material is embedded in that groove. Consequently, the joining strength is intensified.
