In the putter, a head(100) is mounted on one end of a shaft(200), and a grip is mounted on the other end of the shaft(200). The head includes a hitting portion and a direction indicating portion(20). On the front surface of the hitting portion, a hitting surface(110) is formed. The direction indicating portion(20) is respectively formed on both side ends of the hitting portion, and extends to the rear of the head in a straight line. The direction indicating portion(20) and the hitting portion are arranged such that the bottom of the hitting portion does not come in contact with bottom when the bottom of the direction indicating portion is put on a flat surface.
