摘要

An optical-element holding device includes an elastic member that presses an optical element with an elastic force in a direction orthogonal to an optical axis of the optical element and orthogonal to a longitudinal direction of the optical element, and a support member that forms a pair with the elastic member and supports the optical element against a pressing force of the elastic member. At least three pairs of the elastic member and the support member are provided.
