Zusammenfassung:PROBLEM TO BE SOLVED: To provide a light amount adjustment device and an optical device that enable a cost down and miniaturization with a relatively simple configuration.SOLUTION: A light amount adjustment device comprises: an optical path formation substrate that has an aperture part forming an optical path; a base substrate to which the optical path formation substrate is mounted; a light amount adjustment member that is arranged between the optical path formation substrate and the base substrate, and adjusts a light amount by opening and closing the aperture part; and a drive part that drives the light amount adjustment member. The drive part is configured to be embedded and anchored on one surface side of a base member serving as a mount side of the optical path formation substrate. A low cost and miniaturization can be achieved with a relatively simple configuration.
