PROBLEM TO BE SOLVED: To provide a resonance tag which is inexpensive and thin and having a satisfactory communication characteristic. SOLUTION: This resonance tag consists of an insulating base 3 composed of a dielectric, a 1st antenna coil formed on the front face side of the base 3, a 2nd antenna coil 12 formed on the rear face side of the base 3 and cover sheets 6 stuck to the front and rear faces of the base 3 through adhesives 5. The 1st antenna coil 11 and the 2nd antenna coil 12 are arranged oppositely to each other through the base 3 while the directions of their windings are formed reversely to each other, seen from one face side of the base 3. The conductor widths of the respective antenna coils 11 and 12 arranged oppositely through the base 3 can be different from each other in order to easily manufacture the resonance tag having the satisfactory communication characteristic. |
