Abstract

See full text

It is an object to provide a stamper manufacturing method capable of shortening a time taken for manufacturing a stamper without requiring special equipment such as a dry etching device. The stamper manufacturing method comprises the steps of forming a photoresist layer (6) on one of surfaces of a conductive substrate (1), exposing a desirable portion of the photoresist layer (6), developing the photoresist layer (6), forming an electroforming body (8) on the substrate (1) in a portion from which the photoresist layer (6) is removed at the developing step, and carrying out washing to remove the photoresist layer (6) from the substrate (1).
