First, from an original plate such as a photoresist on which a relief pattern is formed, a metal mold or a metal mold or a resin mold (having heat and pressure emboss resistance) and an embossed body (in this specification,
The object to be embossed is a method in which a thermoplastic resin sheet or film is adhered, and pressure is uniformly applied to the entire surface by a flat press machine while simultaneously applying heat to reproduce the relief pattern on the object to be embossed. .. However, in this method, a clear step is formed at the boundary between the embossed portion and the non-embossed portion on the embossed body.
