1. A method for manufacturing an optical lens using a substrate including a first layer, a second layer and a third layer, comprising the steps of:

  • forming a lens surface on a surface of the first layer of the substrate; and

    forming a lens holding section that holds a lens region including the lens surface and an edge section around the lens surface, the lens holding section being formed by removing the third layer, with the exception of a section of the third layer that corresponds to the lens holding section, until the second layer is exposed at a rear surface of the substrate.
