A light control apparatus that controls the amount of light passing therethrough by blocking part of an incident light flux, includes: a pair of pivotal members having pivotal axes extending along a direction substantially perpendicular to a central axis of the light flux; and a pair of light blocking members held by the pair of pivotal members and changing the size of a light blocking area as the pair of pivotal members pivot, the light blocking area blocking part of the light flux, wherein the pivotal axes are located in positions that overlap with an area where the light flux passes, and the pair of light blocking members are located in positions that do not overlap with the pivotal axes.
