1. A wireless transponder comprising:
- a receiver unit that receives an electromagnetic input signal;
an input converter unit that converts into an acoustic wave the electromagnetic input signal received by the receiver unit;
a delay unit provided in a direction in which an acoustic wave generated by the input converter unit propagates;
an output converter unit that converts into an electromagnetic output signal the acoustic wave that has propagated inside the delay unit; and
a transmitter unit that transmits wirelessly the electromagnetic output signal generated by the output converter unit.
