PROBLEM TO BE SOLVED: To provide a power distribution circuit or the like separating a fundamental wave from a secondary harmonic wave with a simple configuration, and also to provide a power distribution circuit or the like successively separating the fundamental wave from the 2<SP>k</SP>harmonic waves (k=1-n) with a simple configuration. SOLUTION: The power distribution circuit is provided with: a fundamental wave output means outputting the fundamental wave included in an input wave inputted from an input terminal to a fundamental wave output terminal; and a secondary harmonic wave output means outputting the secondary harmonic wave included in the input wave inputted from the input terminal to a secondary harmonic wave output terminal. The fundamental wave output means is provided with an inter-digital capacitor having an electrical length in a range of±10% before and after a 1/4 wavelength in the frequency of the fundamental wave. The secondary harmonic wave output means is provided with: a first transmission line having the electrical length in a range of±10% before and after the 1/4 wavelength in the frequency of the fundamental wave; and a tip-open stub having the electrical length in a range of±10% before and after the 1/4 wavelength in the frequency of the fundamental wave.
