发明名称 Hollow golf club head
摘要 A golf club head of the present invention includes a face portion having an impact surface that impacts a golf ball and is made from a metallic material, and a crown portion, a heel portion, a sole portion, and the toe portion that are adjacent to the face portion. In at least two portions from among the crown portion, the heel portion, the sole portion, and the toe portion, at least one from among dissimilar metallic materials that differ from the metallic material of the impact surface and fiber reinforced plastic materials is used in regions along ends that are adjacent to the face portion, within a range of 30 mm from the adjacent ends. Thereby, the golf club has a structure that easily deforms with respect to golf ball impacts, and the face portion deforms more than conventional face portions. The coeffecient of restitution of a struck golf ball therefore increases, the initial velocity of the golf ball increases, and the carry distance increases.
