An object of the present invention is to provide a golf club in which carry does not deteriorate even when a golf ball is struck in a lower position on a face portion. In a golf club constituted by a face portion 4 having a hitting surface, a sole portion 3 which forms a lower portion, and a crown portion 5 which forms an upper portion, the sole portion 3 of a driver club head 1 is improved. A deformation portion B which is capable of elastic deformation is provided in concavoconvex form on the sole portion 3 in a position near the face portion 4. This deformation portion B is constituted by a protrusion 10 which is formed such that the sole portion 3 forms an obtuse angle alpha, and a concave groove 11 which is formed in a direction linking a toe portion and a heel portion by a protrusion protruding towards the crown portion 5. In order to increase hitting distance, restitution in a lower position on the face portion is increased.

In a driver golf head (1) comprising a face (4) having a hitting surface, a sole (3) forming a lower portion, and a crown (5) forming an upper portion, the sole (3) is improved. The sole (3) in the position close to the face (4) was formed into an elastically deformable recess-projection shape, and part of the face (4) was formed into a projecting shape and integrated with the sole (3) to increase rigidity. Using a configuration with increased rigidity and decreased rigidity between the face (4) and sole to obtain an elastically deformable portion and providing a high-rigidity body (12) increased the repulsion force in the lower portion of the face and extended the traveling distance of the golf ball.
