<p>PROBLEM TO BE SOLVED: To provide a dielectric waveguide line with stable characteristics in a high-frequency area which can be used as a transmission line in a multilayered substrate with high density or a semiconductor package, and which can be easily manufactured by using a laminating technique. SOLUTION: This device is provided with a pair of main conductive layers 2 and 3, interposing a dielectric substrate 1, a dielectric waveguide line 5 formed of an area surrounded by a via hole 4 group in two rows formed for electrically connecting the main conductive layers 2 and 3 with intervals less than an interrupting wavelength in a signal transmitting direction, and a sub-conductive layer 6 formed between the main conductive layers 2 and 3, and electrically connected with the via the hole 4 group. Moreover, the dielectric substrate 1 is constituted of ceramic materials, so that the stability of characteristics in a high-frequency area can be improved.</p> |
