The crown member 4, the sole member 5, and the like are welded to each other to form a hollow shell-shaped head shell 6, and a hosel member 7 is fixed to the upper portion of the head shell 6 on the heel side by welding. A weight-added plate 9 whose lower surface 10 has a shape substantially the same as the curved surface of the sole inner surface 8 is joined to the sole inner surface 8 by welding, bonding, or the like. In FIG. 2, after welding, the lower surface 10 of the weight-added plate 9 is in close contact with the inner surface 8 of the sole with an area of about 100%.

The curved shape of the weight-added plate 9 is
Is joined to the sole member 5 by welding, the shape takes into account that it is deformed by thermal strain. That is, the radius of curvature of the lower surface of the peripheral portion of the weight-added plate 9 (before welding) is made (slightly) smaller than the radius of curvature of the corresponding inner surface 8 of the sole portion. When the weight-added plate 9 is joined to the sole inner surface 8 by welding, the weight-added plate 9 receives a force (with cooling) approaching the sole inner surface 8 due to thermal strain, and is indicated by arrows P in FIG. As shown, the central region (excluding the peripheral portion) of the weight-added plate 9 strongly presses (closely contacts) the inner surface 8 of the sole portion. In this manner, the weight-added plate piece 9 has a shape substantially the same as the curved surface of the inner surface 8 of the sole portion when the welding is completed.
Is formed, and the radius of curvature R 1 of the lower surface of the peripheral portion of the weight-added plate 9 is kept slightly smaller than the radius of curvature R 0 of the corresponding inner surface 8 of the sole portion.
