PROBLEM TO BE SOLVED: To prevent the peeling in the boundary part between a substrate and a transparent film by arranging the transparent film between information surfaces and selecting the transparent film in such a manner that its outer edge exists on the side inner than the outer edge of an optical recording medium. SOLUTION: The outer edge of the photosetting resin film 30 arranged on the substrate 1 is so selected as to come on the side inner than the outer edge of the substrate 1 and the inner edge of the photosetting resin film 30 is so selected as to come to the side inner than the inner edge of the substrate 1. In such a case, the generation of air bubbles 40 between the substrate 1 and the photosetting resin film 30 is effectively prevented and the peeling in the boundary part between the substrate 1 and the photosetting resin film 30 is effectively prevented. In addition, the generation of the air bubbles 40 between the substrate 1 and the photosetting resin film 30 is effectively prevented. |
