BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a circuit diagram of a noncontact IC device in a first embodiment according to the present invention;
EXAMPLE An example of the noncontact IC card 10 will be described with reference to FIGS. 3, and 4(A) to 4(D). It is presumed that thirty noncontact IC cards 10 are formed in five rows and six columns on a base sheet. Aluminum films of 20 μ m in thickness for forming the antenna coils 13 and the connecting circuit 15 were formed on both the surfaces, respectively, of a 25 μm thick polyethylene terephthalate film by an electroless plating process and a subsequent electroplating process. The aluminum film formed on the upper surface, i.e., a surface on which IC chips 12 are to be mounted, was subjected to a photolithographic etching process to form the antenna coils 13 and the terminals 113a and 115a to which IC chips 12 are to be connected. Each of the antenna coils 13 was formed by winding a 160 μm wide line in four turns at intervals of 160 μm on the middle sheet 11c of the base card 11. The connecting circuits 15 were formed by processing the aluminum film formed on the other surface of the middle sheet 11c. The through holes 113, 114, 115 and 116 were formed in the middle sheet 11c, and the surfaces of the through holes 113, 114, 115 and 116 were coated with a conductive film by plating. IC chips 12 provided with a 64-byte memory device were bonded to the terminals 113a and 115a formed on the middle sheet 11c by applying heat and pressure to the bumps 121 and 122 of the IC chips 12 with a heater head. The base sheet can be divided into thirty base cards 11.
