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 1.0×10−1to 1.0×10−8S/cm.
