<p>Provided is a stamper for producing a multilayer optical recording medium, which can be produced in simple steps and can be repeatedly used. Particularly, provided is a stamper (115) for producing a multilayer optical recording medium, including: a translucent substrate (111) ; and a translucent inorganic resist layer (112) in which a pit or a guide groove is formed on the substrate. Further, the stamper has an absorptivity of 10% or more with respect to exposure light which is used in patterning the inorganic resist layer, and has a transmittance of 19% or more with respect to an ultraviolet ray which is used when the stamper is used. Furthermore, the inorganic resist layer contains a tungsten oxide or a molybdenum oxide having a composition in which oxygen is lost from a stoichiometric composition.</p> |
