Claim 1:
2. A tag indicating an attribute of the tag by an electromagnetic wave reflection characteristic, the tag comprising:
a substrate; and
a conductor pattern layer formed on the substrate and having n (n is a positive integer of 3 or more) slots,
wherein the n slots
constitute n resonance elements having resonance frequencies different from each other, and are disposed adjacent to each other in such a manner that resonance lengths of the resonance elements are sequentially shortened, and
when irradiation with the electromagnetic waves is performed, a Q value of a resonance peak appearing at a resonance frequency of a kth (k is an integer of 1 to n−1) resonance element counted from a resonance element with a longer length of the slot among the n resonance elements is higher than a Q value of a resonance peak appearing when a resonance structure of the tag is configured by the kth resonance element alone.
