Abstract
There is provided a method for manufacturing an optical element comprising a base material, and a stack covering of layers formed on the base material. The method of the present disclosure comprises a multi-layers forming step for forming an optical multi-layered part of the stack covering, and an outermost surface forming step for forming an outermost surface part of the stack covering. A pressure condition for the formation of the stack covering is made discontinuous between the multi-layers forming step and the outermost surface forming step. In the outermost surface forming step, a silicon oxide-containing layer is formed prior to a formation of a fluorine compound-containing layer.
