Abstract
RFID tag RFIC modules are provided with each module including an RFIC, an antenna connection first electrode, an antenna connection second electrode, an RFIC connection first electrode, an RFIC connection second electrode, an impedance matching circuit that matches impedance between the RFIC and an antenna, and a rectangular substrate. A first coil and a second coil of the impedance matching circuit are juxtaposed in/on the substrate, and a straight line passing through center of gravity of the coil opening of the first coil and center of gravity of the coil opening of the second coil is inclined with respect to one side of the substrate, and directions of this inclination are different between the first RFIC module and the second RFIC module.
