1. A wood type golf club head comprising:
- a toe located at a front of said head;
a sole located at a bottom of said head;
a heel located at a rear of said head;
a ball-striking face located in a central position of said head between said toe and said heel, said ball-striking face having front and rear sides; and
a neck leading from said heel to a shaft of a golf club to which said head is to be connected, wherein a point, at which a center of gravity of said head is located, is positioned on said rear side of said ball-striking face, and a length of an imaginary perpendicular line which is drawn from said point at which said center of gravity of said head is located to a longitudinal axis of said shaft of said golf club to which said head is connected, is at least 35 mm.

Abstract
This invention provides golf club heads wherein a distance between the point of gravity center (O) of a head and the longitudinal axis of a club shaft is made longer, so that an axial moment of inertia about the shaft is greater. The golf club heads have advantageous effects that owing to great axial moment of inertia about the shaft, their ball-striking faces can be impacted against a ball without deviating upon swinging, and even when a ball is hit with a spot outside a sweet spot, the directional behavior and driving distance of the struck ball are improved.
