Abstract
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 α, 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.
