2. Description of the Related Art As shown in FIG. 1, a well-known conventional golf club grip is formed by spirally winding an elongated band-shaped coating layer B around the outer periphery of a sleeve A. Since such a winding connection is performed by an artificial method, a phenomenon that the coating layer B having a considerable length is too long or insufficient after winding due to an artificial factor such as a winding force, a position, and a distance, At this time, the manufacturer had to remove the coating layer B and wind it again. This wasted work and time, and the adhesiveness of the coating layer B was lost due to repeated removal and adhesive work, resulting in unstable product quality.

[0003] Furthermore, the above-mentioned coating layer B is an elongated belt-like body, and therefore, in a specific area of the coating layer B, a non-slip zone (block, convex body) or a cushion pad cannot be provided, and therefore, it is difficult to use. The utility and comfort of known golf club grips were not ideal.
