<P>PROBLEM TO BE SOLVED: To provide an information recording medium such as an IC card on which a contact type IC chip and an external terminal can be mounted while antenna performance(electromotive force or anti-collision performance) is kept satisfactory as it is compared with the case of a medium(non-contact type IC card or the like) having single non-contact type equipment of IC specifications. <P>SOLUTION: This IC card 1 is provided with a supporting body, an antenna coil 5 formed like a coil, a non-contact type IC chip 4 connected to the antenna coil 5 and a contact type IC module 3 mounted on a support body. When the IC cards 1 and 1 are arranged so as to be faced to each other as anti-collision measures, the antenna 5 is formed so that their corner parts can not be overlapped with each other, and an outer peripheral side by-pass part 8 by-passing the contact type IC module 3 to the outer peripheral side and an inner peripheral side by-pass part 7 by-passing the contact type IC module 3 to the inner peripheral side are formed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
