ABSTRACT:
A plurality of signal lines are provided on one main surface of a dielectric substrate. A plurality of other signal lines are provided on the other main surface of dielectric substrate. The plurality of signal lines on one main surface and the plurality of other signal lines on the other main surface are provided so as to extend in parallel to one another. A ground pattern having its potential fixed is provided between neighboring signal lines on one main surface, and a ground pattern having its potential fixed is provided between neighboring signal lines on the other surface. According to such a structure, a microstrip line that can include a larger number of signal lines on the main surfaces of the dielectric substrate, without increasing a size of the dielectric substrate is obtained.
