PROBLEM TO BE SOLVED: To provide a transmission line connection structure of a small loss in radio equipment of a microwave band or more. SOLUTION: A non-radiating rectangular coupling slot 12 is provided on a metal sheet 11 having a thickness with a mechanical strength and a heat radiating effect, dielectric substrates 1, 6 are stuck on both surfaces of the metal sheet 11, the dielectric substrates 1, 6 are equipped with microstrip lines 2, 7, and the microstrip lines 2, 7 are electromagnetically coupled by the rectangular coupling slot 12, thereby realizing the transmission line connection structure of the small loss in spite of a simple configuration.
