Contactlessly readable tag, method for manufacturing contactlessly readable tag, identification device, and identification information determination system

A method of manufacturing a contactlessly readable tag including a metal pattern layer, a conductive layer, and an intermediate layer that has a relative permittivity of 0 or more and 2.5 or less and that is provided between the metal pattern layer and the conductive layer, the method comprising:

• printing in which the metal pattern layer is formed by inkjet printing, by screen printing, by thermal printing, by flexographic printing, or with a dispenser, wherein
• the metal pattern layer includes a metal part whose arrangement pattern corresponds to identification information, and
• the identification information is configured to be identified based on information on an electromagnetic wave that is reflected by the contactlessly readable tag in response to irradiation of the contactlessly readable tag with an electromagnetic wave.

A method of manufacturing a contactlessly readable tag including a metal pattern layer, a conductive layer, and an intermediate layer that has a relative permittivity of 0 or more and 2.5 or less and that is provided between the metal pattern layer and the conductive layer, the method comprising:

• valley-folding in which the metal pattern layer is arranged on each of both surfaces by folding the tag with the conductive layer side being inside, wherein
• information identifying the contactlessly readable tag is configured to be identified based on information on an electromagnetic wave that is reflected by the contactlessly readable tag in response to irradiation of the contactlessly readable tag with an electromagnetic wave, and
• the metal pattern layer is provided closer to a reading surface of the contactlessly readable tag than the intermediate layer.
