Abstract
A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.
