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). |
