Abstract
This invention provides an improved hollow golf club head having a sole portion and a crown portion, wherein the golf club head is configured so as to increase the launch angle of a ball so that the traveling distance of a golf shot can be increased. In particular, the sole portion and the crown portion of the hollow golf club head are configured such that the ratio of a rigidity of the sole portion to a rigidity of the crown portion is 1:0.1 to 0.8 and, as a result of such a configuration, the launch angle of a hit ball is increased.
