To provide an optical element configured so that distortion caused on an optical effective surface by fixing can be reduced or preferably eliminated, and an optical device having the optical element.

The optical element includes the optical effective surface and a holding part for fixing the optical element. The holding part includes a part connected to the optical effective surface, which is provided to have a stepped part between the part connected to the optical effective surface and the optical effective surface, and a cutout is formed in the part connected to the optical effective surface.
