PROBLEM TO BE SOLVED: To provide an optical element equipped with a light-shielding film having high solvent resistance and capable of exerting excellent properties in environmental stability.SOLUTION: An optical element includes a base material and a light-shielding film on part of the base material. The light-shielding film includes a resin and a coloring agent. The resin is a cured product of an epoxy resin containing a monocyclic unsubstituted aryl group, a polycyclic unsubstituted aryl group, a monocyclic substituted aryl group or a polycyclic substituted aryl group.SELECTED DRAWING: Figure 6 【課題】 本発明は、耐溶剤性が高く、環境安定性に優れた特性を発揮する遮光膜を設けた光学素子を提供する。【解決手段】 基材と、前記基材の一部に遮光膜を有する光学素子であって、前記遮光膜は、樹脂と、着色剤とを含有し、前記樹脂は、単環の無置換アリール基、多環の無置換アリール基、単環の置換アリール基、又は、多環の置換アリール基を有するエポキシ樹脂の硬化物であることを特徴とする光学素子。【選択図】 図６
