Non-contact IC tag
A non-contact IC tag includes an insulating substrate, an IC tag having an IC chip and a matching-circuit equipped dipole antenna connected with the IC chip, and a first and second parasitic antenna both provided at the other side of the insulating substrate. The matching-circuit equipped dipole antenna has two antenna sections, a connecting terminal section and a matching circuit section. Projection images of the first and second parasitic antennae onto the one side of the insulating substrate respectively overlap at least portions of the two antenna sections of the matching-circuit equipped dipole antenna. The first and second parasitic antennae are made electrically conductive by a connected portion, and the projection images of the first and second parasitic antennae, and the connected portion onto the one side of the insulating substrate do not overlap the IC chip and the connecting terminal section of the matching-circuit equipped dipole antenna.
