Abstract: A golf club head 2 is provided with a head body h1 and a CFRP member 16. The CFRP member 16 constitutes at least a part of a crown 6 or at least a part of a sole 8. The CFRP member 16 has a UD lamination part 18 having laminated UD layers. Orientation of a fiber is substantially set to three directions in the UD lamination part 18. When the three directions are a first direction, a second direction, and a third direction, preferably, an angle of the second direction to the first direction is substantially +60 degrees, and an angle of the third direction to the first direction is substantially −60 degrees. Preferably, the UD lamination part 18 has a lamination symmetrical property in a fiber orientation angle. Preferably, the number of layers of the UD lamination part 18 is 5 or greater and 12 or less.
