Abstract: A discrimination medium, which can have much information, can be produced on a small scale at low cost, and enables change of a sticker design at low cost, is provided. The discrimination medium includes an optically transparent first substrate on which a cholesteric liquid crystal layer is formed, the cholesteric liquid crystal layer being formed with a fine asperity used for displaying a hologram, an optically transparent second substrate on which a print layer is formed, the print layer having a predetermined pattern made of ink and having a transparent portion without the ink of the pattern around the pattern, the pattern reflecting or absorbing a light of a predetermined wavelength, and a transparent adhesive layer, wherein the optically transparent first substrate, the optically transparent second substrate, and the transparent adhesive layer, are disposed in turn from a side checked visually.
