PROBLEM TO BE SOLVED: To provide a high-frequency rectifier circuit capable of suppressing drop of a step-up voltage due to signal leakage of a diode element or the like even in a high-frequency band.SOLUTION: A high-frequency rectifier circuit comprises: an input terminal for inputting a high-frequency signal; a capacitive element whose one end is connected to the input terminal; a matching circuit whose one end is connected to the other end of the capacitive element; a diode element whose cathode is connected to the other end of the matching circuit; a filter circuit connected to the other end of the matching circuit; a transmission line whose one end is connected to the anode of the diode element and whose other end is grounded; and an output terminal for outputting a DC signal from the other end of the filter circuit. When a prescribed voltage is applied to the diode element in a reverse direction, reactance components of a series body including the diode element and the transmission line resonate in seri
