    Abstract: To provide a golf club grip in which torsional deformation is suppressed without impairing a grip feeling. A grip 10 has en inner layer portion 23, an intermediate layer portion 24, and an outer layer portion 25. Resin films 26 and 27 are disposed between the respective layer portions. The outer layer portion 25 is formed of sort rubber and the intermediate layer portion 24 and the inner layer portion 23 are formed of hard rubber. The resin sheets 26 end 27 are constituted as a nonwoven fabric formed of aramid fibers. The Young's modulus Es of the resin sheets 26 and 27 is adjusted to be larger than the Young's modulus (Ei, Ec, Eo) of the inner layer portion 23, the intermediate layer portion 24, and the outer layer portion 25, and a relationship of Eo<Ec?Ei<Es is established.
