CERAMIC ELECTRONIC PARTS AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a ceramic electronic parts which can facilitate fine adjustment of resonance frequencies for a dielectric coaxial resonator or a dielectric coaxial filter and also can be produced in an extremely easy process by screwing a screw body into a through-hole via a junction member. SOLUTION: The coating and baking processes are given on the inner wall surface of a ceramic block body 2 of a dielectric coaxial resonator 1 and also on the outer wall surface excluding at least an end face. Thus, an inner conductor 4 and an outer conductor 5 are formed on the inner wall and outer wall surfaces of the body 2. Then a junction member 6 is attached to one of both end parts of a through-hole 3 formed on the end face, and a screw body 7 is screwed into the through-hole 3 via the member 6. The screwing degree of the body 7 is adjusted to the through-hole 3 while the resonance frequency is measured, and the resonance frequency is set at a desired value. In such a production method of the resonator 1, a ceramic electronic parts that is adjusted to the proper resonance frequency can be obtained in a simple process.
