ABSTRACT:
An iron-type golf club head having a larger sweet area while insuring a strength of a head. A back surface 1A of a metallic head body 1 is formed with plural rectangular cavities 5, 5A of different dimensions, opposite to the face 4 of the head body 1. The cavities 5, 5A are formed by forging, thus forming even and fine tissues and grain flow. Accordingly, the toughness and durability of material can be enhanced, so that the face 4 can be made thinner to a 1.0 to 3.5 mm thickness for an optimal weight distribution. As a result, a larger sweet area can be realized without damaging a strength of head.
