Structural color developing member and tire
A structural color developing member includes: a base material including a surface, at least a portion of which is provided with a fine ridged/grooved structure formed at a constant arrangement pitch, the base material developing a structural color by the fine ridged/grooved structure; and a color developing layer layered on a surface of the fine ridged/grooved structure.
