A power combiner having a plurality of power amplifiers which are even-numbered, a plurality of series-connected branch circuits for respectively distributing input power to the plurality of power amplifiers, and a plurality of series-connected combiners for combining the respective output power of the plurality of power amplifiers. In the case of any one of such combinations as to equalize electric lengths of transmission lines for connecting between two power amplifiers selected from the plurality of power amplifiers, the combinations each being established by using all of the plurality of power amplifiers once, the electric lengths at which the any one of the combinations are established, take lambd/2i (where lambd=wavelength of fundamental wave, and i=positive integer).
