Abstract

A solid-state displacement element includes an inorganic layered compound having a layered structure and an organic substance inserted between layers of the inorganic layered compound. The solid-state displacement element expands or contracts in the lamination direction of the inorganic layered compound when irradiated with controlling light. An optical element and an interference filter using the same principle of expansion or contraction as that in the solid-state displacement element are also disclosed.
