A method includes: a main body processing step of forming a lens main body having the concave lens surface; a molding step of coating a molding resin on the concave lens surface, pressing a microstructure forming mold, having a molding surface portion transferring the reflection preventing part formed on the surface of a deformable base body part thereof, against the concave lens surface, and curing the molding resin; and a mold release step of exerting a moment of a force relating to the surface top of the molding surface portion so as to deform the base body part to gradually separate the microstructure forming mold from an outer peripheral side thereof in a direction in which the concavo-convex shape of the reflection preventing part extends, thereby performing mold release. |
