Abstract
A production method of a mold having a recessed pattern includes: a plate precursor preparation step of preparing a plate precursor having a pedestal on which a protruding pattern is disposed; a resin plate preparation step of preparing a thermoplastic resin plate having a recessed step portion; and a resin plate precursor production step of producing a thermoplastic resin plate precursor. The plate precursor comprises a substrate having a larger area than the pedestal in a plan view on a side opposite to a surface of the pedestal on which the protruding pattern is disposed. An edge portion where a side surface of the pedestal and the substrate are in contact with each other has a through-hole penetrating the substrate along the side surface of the pedestal.
