PROBLEM TO BE SOLVED: To provide a small-sized coaxial power combiner with excellent wide band characteristics in an LIHF frequency range. SOLUTION: This combiner is provided with a combiner line 1, three input lines 2, 3 and 4 connected to the combiner line 1, three lines 5, 6 and 7 for impedance conversion successively and coaxially connected to the combiner line 1 and an output terminal 8 connected to the projected end part of the line 7 for the impedance conversion. The input lines 2, 3 and 4 are arranged so as to be perpendicular to the combiner line 1 and be perpendicular and point symmetrical with each other centering the line 1. The lines 5, 6 and 7 for the impedance conversion are formed integrally with the line 1. The lines 5, 6 and 7 for the impedance conversion are the equal length and the line length is (1/4)λ.
