Abstract: A mold which is processed by ion beam irradiation or electron beam irradiation and in which a throughput of the mold is high and a decrease in the throughput or electrostatic discharge due to charging does not occur, a method of producing the mold, and a method of producing a molded article produced using the mold. When molding a plastic resin, at least one of a cavity and a core is provided on the surface of a conductive glass substrate. A method of producing a mold for molding a plastic resin or the like includes forming at least one of a cavity and a core by irradiating an ion beam on the surface of a conductive vanadate glass substrate that contains vanadium pentoxide (V2O5) as a main component and that has an electric conductivity in the range of 1.0×10?1 to 1.0×10?8 S/cm.

Abstract: An object of the present invention is to provide a Peltier device capable of retaining a certain temperature at a high accuracy by using a conductive glass consisting primarily of vanadate as an electrode, excellent in handleability, easy in temperature regulation, excellent in stability of cooling performance, capable of securely preventing an electrode from corrosion resulting from chemicals or dew condensation etc., and excellent in reliability and durability of the electrode. The Peltier device has a heat absorbing portion and a heat emitting portion, in which at least the electrode of the heat absorbing portion is formed with the conductive glass consisting primarily of vanadate.
