Abstract
In construction of a wood club head having a main body of a hollow metallic shell construction, the face thickness is limited to 2 to 4 mm and the entire head volume is limited to 190 cc or larger for enlargement of its sweet spot. The enlarged sweet spot assures a long flying distance of a ball in an intended direction through its improved mating with the ball at the very moment of striking.
