PROBLEM TO BE SOLVED: To improve a stickiness of the surface of a hose without using a partial crosslinked resin. SOLUTION: The surface of the hose incorporates a plurality of synthetic resins different in molecular weight and molded under heat. By this the particles of the high molecular weight synthetic resin remain in the molten, low-molecular weight synthetic resin like fish eyes to result in the formation of the fish eyes on the hose surface, and the fine unevenness due to these fish eyes causes the hose surface to be a low frictional surface.
