1. A container comprising:

  • an electromagnetic coupling module including a radio IC chip and a feeder circuit board on which the radio IC chip is mounted, the feeder circuit board including a feeder circuit including a resonant circuit that includes an inductance element and has a predetermined resonant frequency; and

    a radiator that is electromagnetically coupled to the inductance element of the feeder circuit board;

    whereinthe feeder circuit board is defined by a multilayer board and the resonant circuit of the feeder circuit is disposed within the multilayer board;

    the electromagnetic coupling module is attached to an inner surface of the container;

    the radiator is attached to an outer surface of the container, and the radiator is arranged to radiate a transmission signal supplied from the resonant circuit through electromagnetic coupling and/or to supply a reception signal to the resonant circuit through electromagnetic coupling.
