ABSTRACT:
In order to transcribe a pattern without seams of a photomask onto the whole or part of a die having a three-dimensional shape, a general-purpose polyester film coated with a photosensitive material is used as a photomask and, after forming a pattern, the photomask is struck through vacuum molding or the like to a die molded into the same shape as that of a die to be exposed and developed.
