PROBLEM TO BE SOLVED: To provide a dielectric waveguide line which is used for a transmission line in the high density wiring board with high density, coupled with other high frequency transmission lines, easily manufactured by using a lamination technology and whose characteristics are made stable in a high frequency region and to provide the wiring board. SOLUTION: A dielectric waveguide line 5 is formed with a region surrounded by a couple of main conductor layers 2, 3 formed in parallel with a dielectric body 1 inbetween and two-line of viahole groups 4 formed to connect electrically the main conductor layers 2, 3, a slot hole 7 is formed to at least one of the main conductor layers and coupled electromagnetically with a microstrip line or a coplaner line. |
