ABSTRACT:
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.
