FLEXIBLE IC MODULE AND METHOD OF ITS MANUFACTURE, AND METHOD OF MANUFACTURING INFORMATION CARRIER COMPRISING FLEXIBLE IC MODULE

摘要

There are provided a flexible IC module utilizable for the production of contactless IC cards and a method for producing an information carrier using the flexible IC module. An IC chip 1 and a coil 2 are embedded in a flexible substrate 3 comprising a nonwoven fabric or the like having compressibility in the thickness direction, self-pressure bonding property and resin impregnation property. This flexible IC module is produced in the following procedure. 1 &cir& A first nonwoven fabric 12 having compressibility in the thickness direction, self-pressure bonding property and resin impregnation property is placed on a bottom force 11. 2 &cir& An IC chip and a coil are placed on the first nonwoven fabric after positioning them. 3 &cir& A second nonwoven fabric 13 is superposed on the IC chip and coil. 4 &cir& A top force 14 is pressed onto the second nonwoven fabric, and the first and second nonwoven fabrics, the IC chip and the coil are integrated by hot pressing.
