ABSTRACT:
An iron or putter golf club head having a larger sweet area and the lower center of gravity. Weights 12a and 13a of beryllium copper alloy are provided along peripheral portions of a head body 11a of titanium alloy at its face 1a and back 2a side respectively. Specifically, the back weight 13a has a weight-sole portion 20a integrally extending down to a sole 3a. The weight-sole portion 20a is widened at its toe and heel sides relative to its intermediate portion. Thus, the weight distribution of the head is capable of being greatly concenterated on the peripheral portion of the head to enlarge a sweet area. In addition, owing to the weight-sole portion 20a, the center of gravity can be effectively lowered.
