Abstract
A production method of a mold includes: preparing a plate precursor having a protruding pattern formed of protrusions in a pattern presence region on a base, and a thermoplastic resin sheet; determining a position at which the plate precursor is to be pressed against the thermoplastic resin sheet by moving the plate precursor and the thermoplastic resin sheet relative to each other; and forming a recessed pattern on the thermoplastic resin sheet by pressing the protrusions of the plate precursor which is heated against the thermoplastic resin sheet at a position where a part of the pattern presence region of the plate precursor excluding the protrusions is separated from a surface of the thermoplastic resin sheet, cooling the plate precursor in a state in where the pressed protrusions and the thermoplastic resin sheet are in contact with each other, and separating the plate precursor from the thermoplastic resin sheet.
