Abstract: A light-amount adjusting apparatus includes a plurality of light-amount adjusting blades that causes a size of a light-passing aperture to change by rotation thereof. Each of the light-amount adjusting blades includes a base portion on which a rotation center portion and a driven portion are formed, and a blade portion that overlaps another light-amount adjusting blade in a light-passing direction so as to form the light-passing aperture. A thickness of the blade portion is thinner than that of the base portion. When the plurality of light-amount adjusting blades is rotated to set the light-passing aperture to be smaller than a full-opened aperture, a thickness of a portion that overlaps an adjacent stop blade is thinner than that of a portion that does not overlap the adjacent stop blade in each of the light-amount adjusting blades. The blades have high dimension accuracy, and deterioration of the optical performance of the apparatus is reduced.
