PURPOSE:To enable a mask to prolong its service life by plating a metal in a mask pattern and using thus plated film as a mask pattern. CONSTITUTION:A mask pattern 8 is printed on a copper plate 7, and after an exfoliating agent is coated, electroplating is conducted with the copper plate 7 as an electrode, so that metal contained on a plating liquid is plated into the mask pattern 8 printed on the copper plate 7. And then, the copper plate 7 is taken out, and a plated film 9 is exfoliated form the copper plate and attached onto a glass plate with an adhesive, so that a mask for photo-resist is produced. |
