Golf club head

摘要

There is provided a golf club head capable of reliably preventing a backspin rate from varying in rainfall. A plurality of fine grooves are formed on a face surface 2. When observing a cross-sectional surface perpendicular to the face surface 2 involving a vertical line passing through the center G of gravity of the golf club head 1 with the golf club head 1 set at preset loft and lie angles, an average width of the fine grooves 4 in the cross-sectional surface is 100 μm or less and an average pitch thereof in the cross-sectional surface is 100 μm or less. Hence, the discharge of water can be accelerated by a capillary phenomenon, making it possible to reliably prevent a backspin rate of a golf ball from varying in rainfall.

主权项

1. A golf club head comprising:
a plurality of fine grooves formed on a face surface thereof, said fine grooves having an average width of 100 μm or less in a cross-sectional surface perpendicular to said face surface and an average pitch of 100 μm or less in the cross-sectional surface, when the cross-sectional surface perpendicular to said face surface involving a vertical line passing through the center of gravity of said golf club head is observed, with said golf club head set at preset loft and lie angles.
