PROBLEM TO BE SOLVED: To cover a rugged surface of a substrate without intrusion of bubbles, to easily cover various forms of rugged patterns and to prevent increase of the cost and decrease of workability by pressing the opposite surface of a protective film to a photosensitive layer on a flexible supporting body with a face having a rugged pattern, removing the protective layer and laminating the photosensitive layer on a substrate. SOLUTION: When a photosensitive film on a flexible supporting body is to be laminated on a substrate, one surface of a protective film opposite to the photosensitive layer is pressed with a face having a rugged pattern, then the protective film is removed and the photosensitive layer is laminated on a substrate. As for the face having a rugged pattern used to press, a flat face or a roll face can be used. The rugged pattern may be stripes or grids and is not specified. The surface roughness Ra is preferably 20 to 500% of the thickness of the protective film of the photosensitive film, and more preferably 20 to 150%. The pressure and heating temp. to press the photosensitive layer depend on the fluidity of the photosensitive layer and are preferably 0.5 to 10 kg/cm<2> and 40 to 150 deg.C, respectively. |
