    • PROBLEM TO BE SOLVED: To provide a dielectric device which is suitably made small-sized and low profile and can have a passing band width, an attenuation electrode, and higher order mode characteristics easily and surely adjusted.
      SOLUTION: A first hole 41 of a resonance portion Q1 is bored on an external surface 21 and extends from the external surface 21 to an opposite external surface 22. The first hole 41 has a first inner conductor 61 inside and the first inner conductor 61 is parted by a gap g11 on the surface 21 from an outer conductor film 3. A second hole 51 is bored on an external surface which does not face the external surface 21 and connects with the first hole 41 in a dielectric base body 1 and has a second inner conductor 81 inside. The second hole 51 shifts toward the external surface 21 or 22.
