Abstract
A tag indicating an attribute of the tag by an electromagnetic wave reflection characteristic, the tag including a substrate (), and a conductor pattern layer () formed on the substrate () and having first and second slots () and () disposed adjacent to each other, in which the first slot () constitutes a first resonance element (Qa) having a resonance frequency at a first frequency, the second slot () constitutes a second resonance element (Qb) having a resonance frequency at a second frequency higher than the first frequency, and when irradiation with the electromagnetic waves is performed, a Q value of a resonance peak appearing at the first frequency is higher than a Q value of a resonance peak appearing at the first frequency when the first slot () alone constitutes a resonance structure of the tag.
