    Abstract: This fitting method includes, for example, the following steps A1 to E1: (A1) a step of measuring a plurality of impact conditions using a reference club; (B1) a step of obtaining hit ball arrival point data; (C1) a step of selecting two or more of the plurality of impact conditions as explanation variables and performing multiple linear regression analysis with the hit ball arrival point data as an objective variable; (D1) a step of selecting a specific explanation variable from the two or more explanation variables based on a result of the multiple linear regression analysis; and (E1) a step of determining a recommended club including a specification capable of suppressing variation in the specific explanation variable.

    Abstract: A golf ball 2 has a large number of dimples 8 on a surface thereof. A trajectory of the golf ball 2 is divided into first to fourth segments. An average CD1 of drag coefficients CD and an average CL1 of lift coefficients CL in the first segment are equal to or less than 0.225 and 0.180, respectively. An average CD2 of drag coefficients CD and an average CL2 of lift coefficients CL in the second segment are equal to or less than 0.250 and 0.220, respectively. An average CD3 of drag coefficients CD and an average CL3 of lift coefficients CL in the third segment are equal to or greater than 0.260 and 0.220, respectively. An average CD4 of drag coefficients CD and an average CL4 of lift coefficients CL in the fourth segment are equal to or greater than 0.250 and 0.200, respectively.

    Abstract: A head 2 includes a head body h1, a face part Fp1, and a connecting part Cn1. The face part Fp1 includes a face surface f1 and a face back surface f2. The connecting part Cn1 connects the face back surface f2 of the face part Fp1 and the head body h1 to each other. The connecting part Cn1 may be provided at a position separated from a peripheral edge of the face back surface f2. The peripheral edge of the face back surface f2 may be separated from the head body h1. The face part Fp1 may include a face middle region R1 and a face peripheral region R2. The connecting part Cn1 may be provided only in the face middle region R1.

    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.
