【摘要】An wood-type golf club head having plural cavities formed in a back surface of a head body. A back surface 1A of a metallic head body 1 is formed with plural cavities 5, opposite to a face 4 of the head body 1. The cavities 5 are formed by forging, thus generating even and fine metallic tissues and grain flow. Accordingly, the toughness and durability of the material can be enhanced, so that face 4 can be made thinner to a 1.0 to 3.5 mm thickness for realizing an optional weight distribution. As a result, a larger sweet area can be realized without damaging a strength of head.
