PROBLEM TO BE SOLVED: To provide a resonance tag changeable at least once or more to have desired resonance frequency after forming a resonance circuit. SOLUTION: This resonance tag 10 is composed of a spiral antenna body 12 disposed on one face of a substrate 11; a first electrode 14 and a second electrode 15 disposed facing within the one face; and an insulating part 16 disposed to cover the first electrode 14 and second electrode 15. One end 12a and the other end 12b forming both end parts of the antenna body 12 are connected to one end 14a of the first electrode and one end 15a of the second electrode respectively, and the other ends 14b, 15b of the first electrode and second electrode are formed as open ends and provided with a plurality of projecting end parts in mutually facing positions. Third electrodes individually disposed to cover the projecting end parts through the insulating part 16 are eliminated only at requested parts, and the remaining third electrodes are used as capacitance regulating means.
