A dielectric waveguide line comprises a pair of conductor layers (2) between which a dielectric substrate (1) is sandwiched; and two rows of through conductor groups (4) which are formed to electrically connect the conductor layers (2) to each other at repetition intervals not more than one half of a signal wavelength of a high-frequency signal in a transmission direction of the high-frequency signal, and at a constant width (d) in a direction perpendicular to the transmission direction, the high-frequency signal being transmitted through a region surrounded by the conductor layers (2) and the through conductor groups, wherein the two rows of through conductor groups (4) are arranged to form a linear waveguide line, and wherein auxiliary conductor layers (5) are formed between the conductor layers (2) for electrically connecting to each other the through conductors (3) forming the rows of through conductor groups (4). |
