Abstract
An optical element includes: an optically functional part having a first convex surface and a second convex surface intersecting with an optical axis and facing opposite to each other; and an outer peripheral part provided around the optically functional part, the outer peripheral part having a first outer peripheral surface extending from a periphery of the first convex surface and a second outer peripheral surface extending from a periphery of the second convex surface. The first outer peripheral surface and the second outer peripheral surface each are formed to be tapered. A thickness of the outer peripheral part in an optical axis direction is reduced toward a direction moving away from the optical axis.
