To provide a method for manufacturing an original plate sheet for easily manufacturing the original plate sheet having superior mold releasability.
The method for manufacturing the original plate sheet includes: a hard layer forming process for obtaining a laminated sheet by forming a resin hard layer having a smooth surface on one or both sides of a heat-shrinkable resin film; a process of manufacturing an uneven pattern-formed sheet for deforming the hard layer as if folding by shrinking the laminated sheet by heating so as to manufacture the uneven pattern-formed sheet having an uneven pattern formed on a surface of the hard layer; a metal-containing layer forming process for forming the metal-containing layer formed of a metal or a metal compound on a surface of the uneven pattern formed on the uneven pattern-formed sheet; and a release agent layer forming process for forming the release layer containing a fluorine release agent on an exposed surface of the metal-containing layer.
