ABSTRACT:
A diaphragm unit includes: a plate-like base member having an optical path hole formed therein; diaphragm blades overlapping with each other in an optical axis direction of an optical system, being supported by the base member so as to be movable in directions in which the diaphragm blades approach and depart from the optical axis along a plan perpendicular to the optical axis, and forming a diaphragm opening centered on the optical axis inside the optical path hole; and a driving mechanism adjusting the size of the diaphragm opening by moving the diaphragm blades.
