PROBLEM TO BE SOLVED: To provide a dielectric resonator component which is inexpensive, reduces the number of parts, is small in sized and high in performance. SOLUTION: A dielectric resonator component comprises a dielectric filter 2 including: a dielectric block 21; inner conductors 23A, 23B and 23C formed in a plurality of through-holes formed from the upper surface of the dielectric block to the lower surface thereof; an outer conductor 24 formed on the outer surface of the dielectric block 21 excepting for the upper surface; coupling electrodes 25A, 25B and 25C extending from the inner conductors 23A, 23B and 23C on the upper surface of the dielectric block 21 and formed so as to correspond to the through-holes for coupling the resonators; and input/output electrodes 25X, 25Y formed on the upper surface of the dielectric block 21 so as to be coupled with the coupling electrodes 25A, 25C. A metal cover 4 including a portion facing the upper surface of the dielectric block 21 is added to the dielectric filter 2. A dielectric plate 6 is interposed between a portion of the metal cover 4 facing the upper surface of the dielectric block 21 and the coupling electrodes 25A, 25B and 25C.
