PROBLEM TO BE SOLVED: To satisfy requisites for using the structural color to practical use and, at the same time, enable decoration of a material excellent in a recycling property. SOLUTION: The structure has void parts 11 in the material and is formed of a cyclic structure in which interfaces of the void parts 11 cause light diffraction. Further, the cyclic structure has a regular arrangement which exhibits the structural color. Therein, a plurality of void parts 11 formed on the same surface of the material are respectively formed on spots different depth from the surface of the material. COPYRIGHT: (C)2008,JPO&INPIT
