て設定または調整するのが容易ではなかった。However, in the dielectric resonator device in which a plurality of resonators are provided in one dielectric block in this way, if ones having different numbers of resonators are to be manufactured, the dielectric resonator devices are different from each other. It was necessary to prepare a mold. Therefore, a large number of molds are required to manufacture various types of dielectric resonator devices having different characteristics, which increases the manufacturing cost. Further, since the distance between the resonators is determined by the size and shape of each mold, there is a problem that it is not easy to set the degree of coupling between the resonators. That is, for example, in a conventional dielectric resonator device having a combline structure, the setting or adjustment of the degree of coupling between the resonators and the setting or adjustment of the resonance frequency of each resonator are related to each other due to their structure. However, when one changed, the other changed, and it was not easy to set or adjust both independently.
