Abstract:
[Problem] To provide a resonator that is small and has exceptional electrical characteristics, and a filter and communication device in which the resonator is used. [Solution] A resonator having a shield conductor 10, a columnar body 21, and first dielectrics 12. The shield conductor 10 is configured to include a first conductor 13 positioned on the negative z-direction side, and a second conductor 14 positioned on the positive z-direction side, the shield conductor 10 having a hollow space 19 in the interior thereof. The columnar body 21 is configured from a dielectric or a conductor, has a columnar shape, and is located inside the hollow space 19, the negative-z-direction end of the columnar body 21 being joined to the first conductor 13, and a gap being formed between the positive-z-direction end of the columnar body 21 and the shield conductor 10. The first dielectrics 12 are located inside the hollow space 19, the positive-z-direction ends of the first dielectrics 12 being joined to the second conductor 14, a gap being formed between the negative-z-direction ends of the first dielectrics 12 and the shield conductor 10, and the first dielectrics 12 surrounding the columnar body 21 with a gap interposed therebetween.
