Abstract
An optical element for recording and/or reproducing information of an optical information recording medium, includes an optical element body having an incident surface and an opposite surface opposite to the incident surface, A light flux coming from a light source at an outside is introduced to be incident into an inside of the optical element body and is reflected several times in the inside of the optical element body so that the light flux is converged on the opposite surface; and the incident surface is a refractive surface, is convex toward the light source side and includes an optical axis.
