发明名称 GOLF CLUB HEAD
摘要 <p>A golf club head, comprising a face part having a fiber-reinforced plastic layer including reinforced fibers with different orientation angles. The width of the face of the face part in the toe and heel directions is larger than the height of the face in the crown and sole directions. The mass W<SUB>h</SUB> of the reinforced fibers among the fiber-reinforced fibers included in the fiber-reinforced plastic layer in the range of -55° to +55° including 0° in orientation angle when the direction of the ground-contact face of a golf club when the golf club is disposed at a normal address position is set in a reference direction (0°) is larger than the mass W<SUB>V</SUB> of the reinforced fibers in the range of +55° to -55° including ±90° in orientation angle. As a result, the golf club capable of increasing repulsion while maintaining the durability (strength) of the golf club head can be provided.</p>
