PROBLEM TO BE SOLVED: To provide a radio communication device for which communication disabled areas for a non-contact IC card function hardly occur, and which is able to be mounted with elements at high density.SOLUTION: A non-contact communication antenna includes: a first loop antenna (transmitting/receiving antenna 21) which is connected by radio to an IC card processor in a first region; and a second loop antenna (transmitting antenna 23) which is connected by radio to the IC card processor in a second region whose distance is shorter than that of the first region, and in which a communication characteristic with respect to the IC card processor is more satisfactory than that of the first loop antenna (transmitting/receiving antenna 21). A loop surface of the second antenna (transmitting antenna 23) is arranged parallel to a position of a first distance from a holding-up surface K, and a loop surface of the first loop antenna (transmitting/receiving antenna 21) is arranged parallel to a position of a second distance further separated than the second antenna (transmitting antenna 23) with respect to the holding-up surface K. |
