Abstract
In accordance with the production process according to the present invention, a stamper having a desired pattern for the formation of a disc board can be produced without worsening the working atmosphere or causing any other problems. A novel process for the production of a stamper for the formation of a disc board is provided, which comprises applying an adhesive tape to the surface of a stamper body on which an unnecessary resist remains, and then peeling the adhesive tape off the stamper body so that the unnecessary resist is transferred to the adhesive tape to remove itself from the stamper body.
