Abstract
The present invention relates to a dielectric device that is suitable for miniaturization and height reduction and is surface-mountable. In a resonator unit Q a first hole is provided to a dielectric substarate extends from a surface toward a surface opposite thereto, opens in the surface and has a first internal conductor in the interior. A second hole is provided to the dielectric substarate opens in a surface adjacent to the surface extends from the surface toward a surface opposite thereto, and is connected with the first hole in the interior of the dielectric substarate The second hole has a second internal conductor in the interior, and the second internal conductor is connected to the first internal conductor in the interior of the dielectric substarate
