An RFID module includes an RFIC element, a filter circuit, a matching circuit, and a radiating element. The filter circuit and the matching circuit define an RFID device. The filter circuit includes a first inductance element, a second inductance element, and a capacitor. The first inductance element and the second inductance element are of equal inductance, and are strongly magnetically coupled to each other so as to strengthen magnetic fluxes to each other. With this configuration, an RFID module and an RFID device that include a filter circuit to remove harmonic components of the RFIC element but are not large as a whole are constructed.
