Abstract

An object of the present invention is to provide a golf club grip having excellent abrasion resistance and a high coefficient of friction. The present invention provides a golf club grip comprising an outermost layer, wherein at least a part of the outermost layer is formed from a rubber composition containing (A) a base rubber and (B) carbon black, (B) the carbon black has a DBP absorption amount in a range from 50 cm/100 g to 140 cm/100 g and a CTAB specific surface area in a range from 30 m/g to 160 m/g, a product (amount×DBP absorption amount) obtained by multiplying an amount (g) of (B) the carbon black in the rubber composition with respect to 100 g of (A) the base rubber by the DBP absorption amount (cm/100 g) ranges from 380 to 2600, a product (amount×CTAB specific surface area) obtained by multiplying the amount (g) of (B) the carbon black in the rubber composition with respect to 100 g of (A) the base rubber by the CTAB specific surface area (m/g) ranges from 425 to 3000, and the part formed from the rubber composition has tan δ(30° C., 10 Hz) in a range from 0.100 to 0.280.
