Abstract: A laminate and the like capable of improving the barcode reading accuracy with a configuration having a smaller number of layers is provided. Further, a laminate and the like capable of further improving the barcode reading accuracy and further reducing the size of a barcode portion even when applied to a conventional layer configuration is provided. The laminate includes a colored barcode print layer 5, a base material layer 1, and a bead-containing coating layer 7 having beads 7b dispersed in a resin 7a.

Abstract: Provided are an antenna circuit constituent body for an IC card/tag, which enhances a Q value by reducing a permittivity of a resin film of which a base material is made; and an IC card. The antenna circuit constituent body includes the base material made of resin film; and circuit pattern layers formed on each of both sides of the base material and made of aluminum foil. The circuit pattern layer includes a coiled pattern layer. Parts of the circuit pattern layers, which mutually face each other; and a part of the base material, which is interposed between the parts of the circuit pattern layers, constitute a capacitor. The circuit pattern layers are electrically connected by crimping parts. The base material includes a plurality of void-state-air layers. A relative density of the base material with respect to a density of a resin is less than or equal to 0.9.

Abstract: Provided are an antenna circuit constituent body for an IC card/tag, which is capable of enhancing a Q value by reducing a permittivity of a resin film of which a base material is made; and an IC card. The antenna circuit constituent body (10) for an IC card/tag comprises: the base material (11) made of the resin film; and circuit pattern layers (131 and 132) each formed on each of both sides of the base material (11) and made of aluminum foil. The circuit pattern layer (131) includes a coiled pattern layer. Parts of the circuit pattern layers (131 and 132), which mutually face each other; and a part of the base material (11), which is interposed between the parts of the circuit pattern layers (131 and 132), constitute a capacitor. The circuit pattern layers (131 and 132) are electrically connected by means of crimping parts (13a and 13b). The base material (11) includes a plurality of void-state-air layers.
