PROBLEM TO BE SOLVED: To simply form projected patterns on a trial product. SOLUTION: A photosensitive resin film 1 is coated with a negative film 2 having light transmitting sections 21 and light shielding sections 22 corresponding to projected patterns 13 to be formed, and the photosensitive resin film 1 is exposed from outside the negative film 2, and a film 1a after being exposed is bonded on the surface of a product 4 through a bonding agent layer 6, and non-exposed sections 12 of the film 1a are removed to form the projected patterns 13 on the surface of the trial product, and the product is coated from above the projected patterns.
