<p>A wireless tag corresponding to metal having a wider passband (frequency to communication distance) characteristic than before is realized. The wireless tag comprises a first oscillator pattern (21) having a chip connection portion (211) to which a chip is connected and an inductance portion (212) for adjusting impedance match with the chip and a second oscillator pattern (22) to which power is supplied by electromagnetic induction combination via the inductance portion (212).</p>
