Abstract: Provided is a manufacturing method of a pattern sheet having excellent productivity at low costs. The manufacturing method of a pattern sheet includes: a process of producing, using a plate precursor having a protruding pattern formed thereon, a plurality of first molds having a recessed shape, which is an inverted shape of the protruding pattern, from a resin; a process of producing a plurality of metallic electroforms having the protruding pattern formed thereon by electroforming using the first mold; a process of producing a plurality of second molds having a recessed shape, which is an inverted shape of the protruding pattern, from a resin using the electroform; and a process of producing pattern sheets and having a protruding pattern formed thereon using the second mold.

Abstract: There is provided a method capable of manufacturing a mold at low cost, and a method of manufacturing a biocompatible pattern sheet by using the mold. The method of manufacturing a mold having a recessed pattern includes the steps of: forming a silicone resin film by applying a silicone resin solution to a surface of a model having a protrusion pattern; defoaming the silicone resin film by reducing the silicone resin film in pressure; forming the mold by heating and curing the silicone resin film while a base plate is in contact with a face of the silicone resin film, the face being opposite to the model; and releasing the mold from the model after releasing the base plate. The method of manufacturing a pattern sheet uses the mold.
