Abstract
The present invention provides a technique capable of manufacturing a resin stamper at a low cost. A method of manufacturing a plate-shaped resin stamper includes: pressing a resin composite base material against a mother stamper having a pattern formed on the surface thereof by compression molding to transfer the pattern of the mother stamper to the composite base material; and punching the composite base material. In the manufacturing method, the resin composite base material includes at least one curing resin. In addition, during the compression molding, a portion of the composite base material is cured by active energy beams or heat, the pattern is transferred to the composite base material, and the composite base material is punched, thereby manufacturing the resin stamper.
