PROBLEM TO BE SOLVED: To realize a coupling line in which property variation by thickness variation of a dielectric substrate is little, and to improve an yield of the circuit. SOLUTION: The coupling line is provided with the dielectric substrate 1; a ground conductor 2 which is prepared on a main plane of the dielectric substrate 1, a plurality of strip conductors 6 which are formed on another main plane of the dielectric substrate 1, have clips 5, are simultaneously arranged nearly in parallel, and mutually carry out electromagnetic coupling; input and output terminals 4 which are respectively prepared for at least one end of the plurality of strip conductors 6; and internal strip conductors 8 which are prepared inside of the clips 5 with a space and without electrical conductivity to the strip conductors 6, and electrically connected to the ground conductor 2 by connection conductors 7 which penetrate through the dielectric substrate 1.
