ABSTRACT:
A dielectric resonator includes a resonator body having a groove formed in its upper surface adjacent to an outer periphery of a through hole formed through the body. An electrically-conductive film on the inner surface of the groove is electrically connected to an electrically-conductive film formed on the inner peripheral surface of the through hole, via an electrically-conductive film formed on a portion of the upper surface of the body lying between the groove and the through hole. The groove having the electrically-conductive film formed on its inner surface enables the length of the body to be reduced and the overall resonator to have a reduced size.
