摘要

A plastic optical element which can be manufactured at low cost has excellent heat resistance, and furthermore, excellent optical stability, with no optical characteristic change even when it is used for a long period of time. The optical element has a thermosetting resin as a base material, and in the thermosetting resin, particles which absorb or reflect at least infrared rays or ultraviolet rays are dispersed.
