Abstract
An optical apparatus includes an optical element, and an attached member to which the optical element is attached. The optical element and the attached member are adhered to each other by an adhesive while the optical element and the attached member contact each other. The optical element includes a flange part that projects from an outer peripheral surface to an outer periphery direction. The adhesive is adhered so as to cover the flange part in an adhesion area where the optical element and the attached member are applied to each other by the adhesive.
