Abstract: A passive transponder is started up by receiving an interrogation signal and returning a requested response signal. The startup is controlled by an interrogator using a startup control method by judging presence or absence of a return of the response signal while monotonically increasing transmission power of the interrogation signal from an initial value by an amount which is made smaller stepwise every time presence of the return is judged and maintaining the transmission power, after presence of the return is judged, at its value as of the time when presence of the return was judged.
