Golf club head
A head 2 includes a head body h 1 , a face part Fp 1 , and a connecting part Cn 1 . The face part Fp 1 includes a face surface f 1 and a face back surface f 2 . The connecting part Cn 1 connects the face back surface f 2 of the face part Fp 1 and the head body h 1 to each other. The connecting part Cn 1 may be provided at a position separated from a peripheral edge of the face back surface f 2 . The peripheral edge of the face back surface f 2 may be separated from the head body h 1 . The face part Fp 1 may include a face middle region R 1 and a face peripheral region R 2 . The connecting part Cn 1 may be provided only in the face middle region R 1.
1. A golf club head comprising:
a head body having a sole, a top portion and a front portion with a front surface;
a face part; and
at least one connecting part,
wherein
the face part includes a face front surface as a hitting face and a face back surface wherein the face part has a uniform thickness;
the connecting part connects the face back surface and the head body front surface to each other;
the connecting part is provided at a position apart from a peripheral edge of the face back surface;
a peripheral edge of the face back surface is separated from the head body by a clearance of 0.2 mm or greater and 10 mm or less between the face back surface and the head body front surface;
no hollow space is present between the face front surface and the face back surface such that the face part is solid;
the face front surface has a face middle region that is defined as an inner side region of an ellipse A having: a center positioned at a center of the face front surface; a major axis which is half a width in a toe-heel direction of the face front surface; and a minor axis which is half a width in an up-down direction of the face front surface;
the face front surface has a face peripheral region that is defined as an outer side region of the ellipse A; and
when an average CT value in the face middle region is represented by CT1, and an average CT value in the face peripheral region is represented by CT2, then CT2 is greater than CT1.
