Summary:PROBLEM TO BE SOLVED: To provide a small and light-weight radio wave identifying sheet with high productivity. SOLUTION: A spiral loop antenna 2 which is planarly formed by a conductive material, a tuning capacitor 3 which is connected to the loop antenna 2 and a transmitting/receiving integrated circuit 4 which receives electromagnetic waves with a prescribed frequency via the loop antenna 2 so as to transit a previously set identifying signal via the loop antenna 2 are arranged on a sheet- shaped base material 1 which is formed by a non-conductive material.
