| 摘要 |
<p>The present invention relates to a dielectric device that is suitable for miniaturization and height reduction and is surface-mountable. In a resonator unit (Q1), a first hole (41) is provided to a dielectric substarate (1), extends from a surface (21) toward a surface (22) opposite thereto, opens in the surface (21), and has a first internal conductor (61) in the interior. A second hole (51) is provided to the dielectric substarate (1), opens in a surface 23 adjacent to the surface (21), extends from the surface (23) toward a surface (24) opposite thereto, and is connected with the first hole (41) in the interior of the dielectric substarate (1). The second hole (51) has a second internal conductor (81) in the interior, and the second internal conductor (81) is connected to the first internal conductor (61) in the interior of the dielectric substarate (1). <IMAGE></p> |
