A genuine/counterfeit discrimination method, comprising identifying a combination of at least two of an electric field pattern, a magnetic pattern, an electron beam responsive pattern, and reflection or absorption patterns of visible light, ultraviolet light, and infrared light using an electric field, a magnetic field, an electron beam, visible light, ultraviolet light, or infrared light. A genuine/counterfeit discrimination object, wherein a combination of at least two of an electric field pattern, a magnetic pattern, an electron beam responsive pattern, and reflection or absorption patterns of visible light, ultraviolet light, and infrared light can be identified therein using an electric field, a magnetic field, an electron beam, visible light, ultraviolet light, or infrared light. And a genuine/counterfeit discrimination device comprising at least two devices selected from a device for identifying an electric field pattern, a device for identifying a magnetic pattern, a device for identifying an electron beam responsive pattern, a device for identifying a visible-light pattern, a device for identifying an ultraviolet-light pattern, and a device for identifying an infrared-light pattern and further comprising a device for comparing and identifying patterns obtained with these identification devices.
