Abstract:
The invention prevents a resin member from being broken so as to improve durability. The invention provides a golf club head (1) in which at least a part of a crown portion (4) forming an upper surface of the head is formed by a resin member (FR) made of a fiber reinforced resin in which a fiber is oriented in a matrix resin. The resin member (FR) includes a one-way fiber reinforced resin layer in which the fiber is oriented in one direction, and a fiber intersection lamination portion which is laminated so as to differentiate a direction of the fiber. At least two one-way fiber reinforced resin layers which are adjacent in a thickness direction are intersected at an angle of 30 to 130 degrees of the fiber. Further, a compressive strength of the fiber of the one-way fiber reinforced resin layer which is arranged in an innermost side in the fiber intersection lamination portion is set to be equal to or more than 1.3 GPa.
