Abstract
A golf putter (2) includes a head (4), a grip (6) and a shaft (8). The head (4) has a head body (h1) formed of a metal and a face member (f1) formed by an elastic material. A front surface (Ff) of the face member (f1) constitutes at least a part of a face surface (10). A siping (s1) is provided on a back surface (Bf) of the face member (f1). The siping (s1) is not provided on the front surface (Ff) of the face member (f1). It is preferable that the siping (s1) should be extended with bending. It is preferable that a ratio (Ds/Tf) of a depth (Ds) of the siping (s1) to a thickness (Tf) of the face member (f1) should be equal to or higher than 0.2 and should be equal to or lower than 0.8. It is preferable that a width (Ws) of the siping (s1) should be equal to or smaller than 1.0 mm.
