An antenna includes a first loop (11), a second loop (12) which encloses an outer side of the first loop and is separated from the first loop by a slit (14) and both end of which are merged with both ends of the first loop, and IC chip connection parts (13a, 13b) provided in a portion where the first loop and the second loop are merged, wherein a loop length of the first loop and a loop length of the second loop are equal to or shorter than one third of a wavelength corresponding to a desired frequency resonant with an IC chip connected to the IC chip connection parts. |
