There is disclosed an electronic image pickup apparatus including an aperture stop disposed on an optical path reflected by a reflective surface of a first lens unit and having a non-circular aperture in a state in which an area of an aperture of the aperture stop is maximized, and a lens arranged closest to an image side on an optical path extending from the reflective surface to an image surface and having a non-circular shape, each of the shape of the non-circular aperture of the aperture stop and the outer shape of the lens is formed such that a length of the aperture which in a direction along an incident optical axis which enters the first lens unit is smaller than that of which in a direction vertical to the incident optical axis which enters the first lens unit and a reflected optical axis reflected by the reflective surface.
