Abstract
A structural body has an inner layer formed of a resin which does not transmit light with a specific wavelength, an outer layer stacked on the inner layer and formed of a resin which transmits the light with the specific wavelength, and a fine periodic structure provided on at least part of a surface of the inner layer facing the outer layer and having a plurality of photodecomposition generated convex and concave portions. The plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.
