发明名称 OPTICAL ELEMENT AND OPTICAL ELEMENT MANUFACTURING METHOD
摘要 To provide an optical member, formed without generating cracks in a hard coat layer of desired film thickness, and a method of manufacturing an optical member that permits the manufacturing of the above optical member. The optical member of the present invention is characterized by comprising a lens substrate having a curved surface, a porous intermediate layer formed so as to cover an edge portion of the lens substrate in a planar view along an optical axis of the optical member, and a hard coat layer formed so as to cover the lens substrate and the intermediate layer in the planar view; as well as characterized in that the hard coat layer comprises a thick film portion, formed on the edge portion of the hard coat layer and thicker than a center portion of the hard coat layer in the planar view, and when a maximum film thickness of the intermediate layer is denoted as A (µm) and a maximum film thickness of the thick film portion is denoted as B (µm), a relation of A/B being equal to or greater than 3% but equal to or less than 20% is satisfied.
