Abstract

Abstract PURPOSE:To obtain inexpensively an optical part good in accuracy of the surface, by providing a photo-setting resin layer on a plastic substrate surface, and a releasing agent layer on a surface of a matrix for an optical part, bringing the layers into firm contact with each other, irradiating an activation energy beam on the photo-setting resin layer, and separating the matrix at the releasing agent layer from the substrate. CONSTITUTION:A photo-setting resin (e.g. an ultraviolet-curing resin, etc.) layer 2 is formed on the surface of a plastic substrate 1 (e.g. a polymethyl methacrylate resin, etc.), and after the releasing agent (e.g. a polydimethyl siloxane, etc.) layer 4 is formed on the surface of the matrix 3 for the optical part to be duplicated, the photo-setting resin layer 2 and the releasing agent layer 4 are brought into firm contact with each other. Then an activation energy beam (e.g. ultraviolet beam, etc.) is irradiated to set the photo-setting resin layer, and the matrix 3 is separated with the aid of the releasing agent layer 4 from the plastic substrate 1 to obtain the intended optical part.
