PROCÉDÉ DE FABRICATION DE MOULE, PROCÉDÉ DE PRODUCTION DE FEUILLE À MOTIF, PROCÉDÉ DE FABRICATION DE MOULE ÉLECTROFORMÉ, ET PROCÉDÉ DE FABRICATION DE MOULE À L'AIDE D'UN MOULE ÉLECTROFORMÉ
A production method of a mold includes: preparing a plate precursor 10 having a protruding pattern 10A formed of a plurality of protrusions 12 in a pattern presence region 10D on a base 10C, and a thermoplastic resin sheet 20； determining a position at which the plate precursor 10 is to be pressed against the thermoplastic resin sheet 20 by moving the plate precursor 10 and the thermoplastic resin sheet 20 relative to each other； and forming a recessed pattern 20A on the thermoplastic resin sheet 20 by pressing the protrusions 12 of the plate precursor 10 which is heated against the thermoplastic resin sheet 20 at a position where a part of the pattern presence region 10D of the plate precursor 10 excluding the protrusions 12 is separated from a surface 20B of the thermoplastic resin sheet 20, cooling the plate precursor 10 in a state in which the pressed protrusions 12 and the thermoplastic resin sheet 20 are in contact with each other, and separating the plate precursor 10 from the thermoplastic resin sheet 20.
