Abstract
A dielectric resonator including a dielectric block through which an inner conductor formation hole passes; an inner conductor partially formed on an inner surface of the inner conductor formation hole; and an outer conductor formed on an outer surface of the dielectric block. A portion where the inner conductor is not formed is provided on the inner surface of the inner conductor formation hole in the vicinity of one open end portion of the inner conductor formation hole. A stepped portion is provided at a predetermined position on one of the inner surface of the inner conductor formation hole and the outer surface of the dielectric block. Two portions with corresponding resonant characteristics and respective line impedances different from each other are provided with a boundary defined by the stepped portion between the two portions.
