A method for manufacturing a mold having a concave pattern on a concave step portion and a method for manufacturing a pattern sheet.

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a mold having a concave pattern in a concave step portion capable of preventing the flow of liquid, and a method for producing a pattern sheet. SOLUTION: A method for producing a mold 200 having a concave pattern 205 is a method of preparing an original plate 10 having a table 11 on which a protruding pattern 14 is arranged, and a total volume of the protruding pattern 14 and the table 11. A resin plate preparation step of preparing a thermoplastic resin plate 20 having a concave step portion 23 having a volume equal to or less than the same, a positioning step of positioning the protruding pattern 14 of the original plate 10 and the center position of the concave step portion 23, and heating. The protruding pattern 14 and the base 11 of the original plate 10 are pressed against the concave step portion 23 and then cooled, and the original plate 10 and the thermoplastic resin plate 20 are separated to form an inverted concave pattern of the protruding pattern 14. Includes a concave pattern forming step of forming the 25 on the thermoplastic resin plate 20, and a resin original plate making step of making the thermoplastic resin original plate 26 including the concave pattern forming step.
