PURPOSE:To decrease the leakage of an electromagnetic field and to increase the no load Q by making the width of a resonance conductor part of a dielectric member narrower than the width of a grounding conductor part. CONSTITUTION:The resonance conductor is included by narrowing the width of the resonance conductor 7 of the dielectric member 5 than the width of the grounding conductor 6. Thus the resonator is realized where the leakage in an electromagnetic field is less and the no load Q is high. Since the width of the resonator conductor part is narrower than the width of the grounding conductor, the conductors are placed on the side face. In providing the conductor on the side face, the resonator with higher no load Q is obtained. Further, in opening a hole to the conductor provided on the side face, since the leakage quantity of the electromagnetic field is controlled, the resonator is used for a filter requiring a desired coupling quantity.
