Abstract
There is provided a transmission circuit using a strip line which can be formed in three dimensions with simple construction and low cost and which has high reliability. A first microstrip line is formed by sandwiching a dielectric substrate 1 between a first strip conductor 2 provided on a top surface of the dielectric substrate 1 and a first grounding conductor 3 provided on a bottom surface of the dielectric substrate 1. A second microstrip line is formed by sandwiching the dielectric substrate 1 between a second strip conductor 4 provided on the bottom surface of the dielectric substrate 1 and a second grounding conductor 5 provided on the top surface of the dielectric substrate 1. The first strip conductor 2 and the second strip conductor 4 are electrically connected to each other by a connecting through hole 11 provided in the dielectric substrate 1.
