<p>PROBLEM TO BE SOLVED: To suppress generation of burr at a marginal part of an opening pattern in forming the opening pattern by laser processing.SOLUTION: In a method for manufacturing a film forming mask with a structure where a resin film layer 1 provided with the opening pattern 4 having a predetermined prescribed shape and a magnetic metal material layer 2 provided with a clearance 7 having a size where the opening pattern 4 can be included are laminated, the opening pattern 4 is formed by radiating a laser beam to a part of the film layer 1 corresponding to the clearance 7 from both surface sides to penetrate the film layer 2 therethrough.</p> |
