Abstract: A process deciding method in a method of manufacturing an optical element by heating and press-molding an optical material to mold the optical element using a molding die on which a release film is formed, includes a basicity degree identifying process in which a degree of basicity of the optical material is identified; and a removing process determining process of determining whether to perform one or both of first removing process in which an oxidizing substance is removed and a second removing process in which a basic substance is removed from at least one of a surface of the optical material and a surface of the release film by comparing the degree of basicity of the optical material identified in the basicity degree identifying process with a predetermined reference value, before press-molding the optical material.
