An RFIC tag (1A) includes an IC chip (5) and a thin metal plate (10A). The IC chip (5) is mounted approximately in the center of a slit part (10a) on the thin metal plate (10A). The thin metal plate (10A) has connecting parts (10c) at both longitudinal-direction ends fixed on a metal member (2) by soldering, and the undersurface of the slit part (10a), which has an L-shaped slit (6A) thereon, is lifted a predetermined height (h) from the surface of the metal member (2). The total length (L2+L1+L2) is 1/4 or shorter than the communication wavelength ». |
