Abstract
In order to solve a problem of a shift of a rebounding direction due to a contact of a golf ball and a ball contact surface of a putter face, while attaining an initial velocity, a striking touch, and a sense of distance, each of which are compared favorably to a metal face, a putter face is arranged including hexagonal posts () each made of material having a higher rigidity than a ball (), the hexagonal posts () having a contact surface () which has contact with the ball (), and impact-absorbing rings () made of material having a lower rigidity than that of the hexagonal posts (), so as to elastically support the hexagonal posts () in a normal direction of the contact surfaces (), wherein the plurality of hexagonal posts () are juxtaposed in an in-plane direction of the contact surfaces () and the contact surfaces () constitute a single surface when the ball () is not in contact with the contact surfaces ().
