Method for producing mold, method for producing pattern sheet, method for producing electroformed mold, and method for producing mold using electroformed mold

摘要

Provided are a production method of a mold (22), a manufacturing method of a pattern sheet, a production method of an electroform (410), a production method of a mold (22) using an electroform (410), and an original (10). The production method includes: preparing an original (10) having an inclined portion (10C) which is formed in an enclosed shape on an outer peripheral portion of a protruding pattern (10A) formed at a center portion on a base and gradually increases in thickness from inside toward outside, and a thermoplastic resin sheet (20); and forming a recessed pattern (20A) on the thermoplastic resin sheet (20) by pressing the original (10) which is heated against the thermoplastic resin sheet (20) at a position where a flat surface of the original (10) and a surface of the thermoplastic resin sheet (20) are separated from each other, cooling the original (10) in the state where the original (10) is pressed, and separating the original (10) from the thermoplastic resin sheet (20).
