Abstract: A method of manufacturing a rubber member includes forming a mask on which pattern structures are arranged at a constant pitch, arranging the mask on a substrate of a mold made of a metal or a semiconductor material and etching the substrate. The method further includes adhering unvulcanized rubber to the substrate, vulcanizing the unvulcanized rubber to form vulcanized rubber, and transferring a fine ridged/grooved structure to a surface of the vulcanized rubber. The fine ridged/grooved structure is formed on at least a part of the surface of the vulcanized rubber as the rubber member, the fine ridged/grooved structure having fine ridged/grooved portions arranged at the constant pitch. A region in which the fine ridged/grooved structure is provided is visually recognizable by a structural color different from colors of other regions.

Abstract: A vehicle tire, as a rubber member, includes, on at least a part of the surface thereof, a fine ridged/grooved structure formed via transfer from a mold and having fine ridged/grooved portions arranged at a constant arrangement pitch, wherein a region in which the fine ridged/grooved structure is provided is visually recognizable by a different structural color from the colors of other regions. The fine ridged/grooved structure is formed on a sidewall portion of the vehicle tire, and the region in which the fine ridged/grooved structure is provided is formed in a shape to display predetermined information.
