Abstract
Abstract A dielectric resonator employing the TM mode as its resonance mode, which is provided with a dielectric base plate on which an electronic circuit is formed and a pair of electrodes formed in face-to-face relation to each other on respective major surfaces of the dielectric base plate. A plurality of through-holes are defined between the pair of electrodes on their circumferential portions and both of the electrodes are connected with each other by way of conductive material formed on the inner surfaces of the through-holes.
