Abstract
The present invention relates to a method of manufacturing a wood type golf club head including a face portion, a crown portion, and a sole portion. The method includes a setting step of setting a surface roughness of the face portion and a step of forming the face portion based on the surface roughness set in the setting step. In the setting step, the larger a moment of inertia of the golf club head is, the larger the surface roughness outside an impact area of the face portion is set, and the smaller the moment of inertia is, the smaller the surface roughness outside the impact area of the face portion is set.

A method of manufacturing a wood type golf club head including a face portion, a crown portion, and a sole portion, comprising:
- a setting step of setting a surface roughness of the face portion;
- and
- a step of forming the face portion based on the surface roughness set in the setting step,
- wherein in the setting step, the larger a moment of inertia of the golf club head is, the larger the surface roughness outside an impact area of the face portion is set, and the smaller the moment of inertia is, the smaller the surface roughness outside the impact area of the face portion is set.
A method of manufacturing a wood type golf club head including a face portion, a crown portion, and a sole portion, comprising:
- a setting step of setting a surface roughness of the face portion;
- and
- a step of forming the face portion based on the surface roughness set in the setting step,
- wherein in the setting step, the larger a bulge is, the larger the surface roughness outside an impact area of the face portion is set, and the smaller the bulge is, the smaller the surface roughness outside the impact area of the face portion is set.
A wood type golf club head including a face portion, a crown portion, and a sole portion, wherein
- the larger a moment of inertia of the golf club head is, the larger a surface roughness outside an impact area of the face portion is set, and the smaller the moment of inertia of the golf club head is, the smaller the surface roughness outside the impact area of the face portion is set.
A wood type golf club head including a face portion, a crown portion, and a sole portion, wherein
- the larger a bulge of the face portion is, the larger a surface roughness outside an impact area of the face portion is set, and the smaller the bulge of the face portion is, the smaller the surface roughness outside the impact area of the face portion is set.
