PROBLEM TO BE SOLVED: To provide a rectification circuit capable of efficiently generating a DC power from a high frequency of a low power. SOLUTION: This rectification circuit 100 includes: a first diode D<SB>1</SB>; an input capacitor C<SB>i</SB>, an input inductor L<SB>i</SB>, a second diode D<SB>2</SB>and an output capacitor C<SB>0</SB>connected in series; and a first inductor L<SB>1</SB>. One terminal of the first inductor L1 is connected to ground and the other terminal is connected to an anode of the first diode D<SB>1</SB>. A cathode of the first diode D<SB>1</SB>is connected to an anode of the second diode D<SB>2</SB>. A cathode of the second diode D<SB>2</SB>is connected to the output capacitor C<SB>0</SB>, and the other terminal of the output capacitor C<SB>0</SB>is connected to the ground. Thus, a load R is connected to the output capacitor C<SB>0</SB>in parallel and the high frequency of 1 MHz to 10 GHz or so is input from the other terminal of the input capacitor C<SB>i</SB>. The rectifying circuit 100 efficiently converts even weak power of 1 mW or less into the DC power. COPYRIGHT: (C)2007,JPO&INPIT
