An optical element of the present invention includes a transparent member having a first refracting surface, a second refracting surface, and a plurality of reflecting surfaces. The transparent member is capable of causing light, which enters the transparent member from the first refracting surface, to be reflected by the plurality of reflecting surfaces and guided to the second refracting surface. An optical path from the first refracting surface leading to the second refracting surface crosses itself inside the transparent member when seen from a direction that is substantially perpendicular to both incident light on the first refracting surface and light exiting from the second refracting surface. The transparent member is capable of guiding the incident light from the first refracting surface to the second refracting surface while reflecting the incident light alternately by at least one first reflecting surface and at least one second reflecting surface, the at least one first reflecting surface being at least one reflecting surface of the plurality of reflecting surfaces which is disposed within a first region, the at least one second reflecting surface being at least one reflecting surface of the plurality of reflecting, surfaces which is disposed within a second region, the first region and the second region being regions on one and the other sides, respectively, of a first plane passing through the transparent member which is taken as a boundary.
