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.
