    Abstract: An iron-type golf club head 4 comprises: a head main body 10 including a face 2, a hosel 6, a sole 4 and a back portion 9 extending upward from the trailing edge Te of the sole; and a weight member 20 having a specific gravity larger than the head main body. The face 2 is provided with score lines 7 extending in the toe-heel direction of the head. The weight member 20 is disposed in the sole and extends in the toe-heel direction across a position in the toe-heel direction corresponding to the center position FC of the score lines. The weight member 20 includes a toe-side first portion 21 extending over the sole 4 and the back portion 9, and a heel-side second portion 22 extending within the sole 4.

    Abstract: It is an object of the present invention to provide a golf club head being lightweight and having a high strength. A head 2 includes a face 4, a sole 8, and a crown 6. The face 4 includes a face surface fs and a face back surface fr. A plurality of projections (A) are provided on the face back surface fr. The projections (A) are point-like in a planar view. An optional first direction and a second direction orthogonal to the first direction are defined in the planar view. Preferably, arrangement regularity of the projections (A) in the second direction is higher than arrangement regularity of the projections (A) in the first direction. Preferably, the first direction is a longitudinal direction; and the second direction is a lateral direction.

    Abstract: Provided is a golf club head capable of realizing a lower center of gravity without a weight member protruding from a sole portion. The golf club head according to the present invention includes a crown portion, a face portion, and a sole portion having at least one recessed portion. The recessed portion is configured to house the weight member such that the weight member does not protrude externally. The sole portion is provided with a raised portion including the recessed portion and protruding downward, and to be at least partially placed on a placement surface in a reference state. A center of the recessed portion is arranged further to a back side in a face-back direction and to a heel side in a toe-heel direction than a center of gravity of the head.
