发明名称 COMMUNICATION SYSTEM, INFORMATION RECORDING MEDIUM, AND RELAY COMMUNICATION DEVICE
摘要 The disclosed communication system, information recording medium, and relay communication device allow communication via electromagnetic induction, allow the use of low-cost information recording media, improve communication stability when information recording media is misaligned or rotated, and provide high IC-chip tolerance to flexion in information recording media. An information recording medium (3-1) has: an IC chip (32-1) that is capable of communication via electromagnetic induction; and a pair of thin conductive sheets (21-1) connected to the IC chip (32-1). A relay medium (2-1) has thin conductive sheets (31-1) and a loop antenna (22-1), with one of said thin conductive sheets (31-1) connected to one end of the loop antenna (22-1) and the other thin conductive sheet (31-1) connected to the other end of the loop antenna (22-1). A read/write device (1-1) has a loop antenna (12-1).
