Provided are a production method of a mold having a recessed pattern in a recessed step portion capable of preventing a liquid from flowing, and a manufacturing method of a pattern sheet.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 having a volume equal to or less than a total volume of the protruding pattern and the pedestal； and a resin plate precursor production step of producing a thermoplastic resin plate precursor, the resin plate precursor production step including a positioning step of positioning the protruding pattern of the plate precursor and a center position of the recessed step portion, and a recessed pattern forming step of forming a recessed pattern having an inverted shape of the protruding pattern on the thermoplastic resin plate by pressing the protruding pattern of the heated plate precursor and the pedestal against the recessed step portion, thereafter cooling the plate precursor, and separating the plate precursor from the thermoplastic resin plate.
