Abstract:
This IC card is provided with a module having an inlet, an adhesive layer covering the module, and a first base material and second base material sandwiching the module with interposition of the adhesive layer. The module is disposed on one face of the first base material with interposition of a viscous layer which has a thickness that varies according to the thickness at each area of the module, and its two ends are narrower than its other parts when viewed from the outer face side of the first base material or the outer face side of the second base material. According to this IC card, it is possible to offer the IC card with a flat surface, and without occurrence of strain in the embedded IC chip.

Abstract:
An adhesive composition comprising natural rubber based particles uniformly dispersed in a radiation setting compound is cured by radiation to make a pressure-sensitive adhesive layer on a substrate, thereby: sufficient adhesiveness is obtained; different fillers sufficiently charged; drying time after application is short; both overall application and pattern application are readily performed; application can be performed on different substrates; and sufficient adhesive strength between the substrate and the pressure-sensitive adhesive layer can be realizes. This adhesive composition may be manufactured by: mixing aqueous emulsion 31 containing the natural rubber based particles 30 and the radiation setting compound 32; elevating a temperature of the mixture while stirring; removing vaporized water in the aqueous emulsion; and replacing the water as the medium wherein the natural rubber based particles are dispersed with the radiation setting compound.
