To provide a putter head having a wide hitting area regardless of the shape over the entire part of the head.

This head is constituted by plural clubfaces having different sweet spots. In addition, the structure to allow simultaneous hitting of a balloon with the ≥2 clubfaces is adopted. The changes in the driving forces to the ball by the offsets of hitting points at the plural clubfaces and the sweet spots 5 and 6 are compensated with each other and the application of the total and nearly uniform driving force is made possible, by which a wide hitting area 11 is obtained.
