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.

Abstract: An identification medium can be used in an opening label, clearly show signs of it having been opened, and also have a superior authenticity-confirming function. The identification medium has a structure including, in the following order as seen from the side of observation: an optical function layer that generates a color shift, a separation layer that is partially formed, a printed layer, and an adhesive layer, in which when an adhesive strength between the adhesive layer and an adherend is set to be Xa, an adhesive strength between the adhesive layer and the printed layer is set to be Xb, and an adhesive strength at a portion in which the separation layer is laminated between the optical function layer and the printed layer is set to be Xc, the adhesive strength of each part is set to satisfy Xa>Xb>Xc or Xb>Xa>Xc.
