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 and a metal reflective layer on a surface of a matrix, bringing them 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 matrix. 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 a releasing agent (e.g. a polydimethyl siloxane, etc.) layer 4 and then a metal reflective film 5 (e.g. an Al deposited film, etc.) are successively formed on the surface of the matrix 3 for an optical part to be produced, the photo-setting resin layer 2 and the metal reflective layer 5 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 2, and the matrix 3 is separated with the aid of the releasing agent layer 4 from the plastic substrate 1 to obtain the intended reflective optical part. |
