<p>Provided is a method for reducing resistance of an antenna circuit for obtaining desired characteristics by reducing wiring resistance to a suitable value while ensuring inductance. An antenna circuit (11) is arranged on a transponder having a carrier frequency band of 13.56MHz. The antenna circuit (11) is composed of a prescribed base material (12), and two antenna conductors (13a, 13b), which are formed of the same conductor patterns configuring antenna coils on the front and rear surfaces of the base material (12), respectively, and are electrically connected in parallel. The thickness of each of the two antenna conductors (13a, 13b) is 5% or more but less than 50% of the total thickness of the two antenna conductors (13a, 13b) and the base material (12).</p> |
