Abstract: A metal pattern forming method has: producing a first base having a pattern of lyophilic portions which have lyophilic properties with respect to a liquid containing a metal component and liquid-repellent portions which have liquid-repellent properties with respect to the liquid containing a metal component; producing a second base which holds the liquid containing a metal component; and transferring the liquid containing a metal component from the second base to the lyophilic portions of the first base by bringing the first base and the second base into contact with each other. With the metal pattern forming method, it is possible to form a metal pattern with high accuracy in which the metal is prevented from adhering to an unnecessary position on the base.

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.

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