PROBLEM TO BE SOLVED: To provide a dielectric filter which can be used in a high frequency band and whose characteristic is satisfactory by providing input/output electrodes by land-like conductor films on one face of each dielectric and ground electrodes by conductor films, which are formed on the other whole face, and removing a part of the conductor film of the ground electrode in a part adjacent to the junction face of a face confronted to the face where the input/output electrodes are formed. SOLUTION: Electrodes 43 and 44 in 1.1×1.1 mm are formed at the center of a surface in 6.0×6.0 mm in the dielectrics (dielectric constant 37) 41 and 42 of rectangular parallelepipeds in 6.0×6.0×2.5 mm for example. The ground electrodes 45 and 46 of the dielectrics, which surround them, are formed. The conductor films are also formed on the other surface except for a junction face. The conductor films are connected with the ground electrodes 45 and 46 and become ground potential at the time of mounting. The dielectrics are exposed on the junction face and the electrodes adjusting connection are formed on a part of the junction face. The width of the electrode is set to be 2.0 mm in the example and the ground electrode on an input/output electrode-side is connected with the ground electrode on the surface which faces said electrode.
