ABSTRACT:
Provided is a light transmissive stamper which does not generate a residue of a curable resin even when the stamper including a support substrate and an inorganic resist is used to mold a substrate. The light transmissive stamper is used when an information pattern of an optical recording medium is formed using a curable resin. The light transmissive stamper includes a light transmissive support substrate, a light transmissive inorganic resist layer having an uneven pattern corresponding to an information pattern formed therein, and a peeling layer provided on a side surface of the light transmissive stamper and having a higher peelability from the curable resin than a peelability from the light transmissive support substrate.
