PURPOSE:To obtain a dielectric filter with high mass-productivity and excellent shield performance. CONSTITUTION:Plural dielectric sheets are laminated and adhered to form an integrated lamination board 1. Plural strip resonance electrodes 2, 3, 4 are formed in parallel to a predetermined adhered face of the plural dielectric sheets and both ends of each strip resonance electrode reach both side faces of the laminated board. Recessed parts 21, 31 are formed by locally removing a part of a side face of the laminated board to which one end of the resonance electrode is exposed. A ground electrode 5(6) is formed to a front (rear) side of the laminated board 1 and side face ground electrodes 9a, 9b are formed to both side faces of the lamination board 1 except the recessed parts. The other end of the resonance electrode is connected to the side face ground electrode. |
