Abstract
[Problem] To provide a golf club grip having excellent anti-slipping performance, and feeling when the grip is wet, and further to provide a golf club grip having excellent durability and an improved head speed. [Solution] The golf club grip comprises a cylindrical portion for inserting a shaft, wherein the golf club grip has a narrow groove region comprising narrow grooves in an occupation ratio of 35% or more per 25 mm2 at at least a part of a surface of the cylindrical portion, and the narrow groove has a width (w) of from 0.1 mm to 0.7 mm and a depth (h) of from 0.1 mm to 1.0 mm. In addition, an interval (d) between the narrow grooves are preferably 1.5 mm or less.
