A light amount adjustment device includes a base member, a rotation member rotatably held with respect to the base member, and a light amount adjustment member engaged with the rotation member and configured to be driven by the rotation member to adjust an amount of passing light. The rotation member includes a first surface area in contact with the base member and a second surface area not in contact with the base member. A surface roughness of the first surface area is greater than a surface roughness of the second surface area.
