PROBLEM TO BE SOLVED: To provide a dielectric filter capable of enlarging the cross-section size of a resonator, easily mounting an electric element, and simplifying a manufacturing process. SOLUTION: This dielectric filter is composed of a capacitor array 11 which is provided with plural coaxial dielectric resonators 10 and an insulating substrate 12 and in which conductor patterns 13 are formed on the opposite faces of the insulating substrate 12 and capacitive coupling between the opposite conductor patterns 13 is used as a capacitor, a coil array 14 in which plural inductances 18 are formed on one face of an insulating substrate 19, and a metallic base 21 provided with a ground terminal 4. In this case, the metallic base 21 is provided with first louvered parts 3 for positioning the mounting of the coaxial dielectric resonators 10, second louvered parts 5a, 5b, and 5c for positioning the mounting of the capacitor array 11, and third louvered parts 6 for positioning the mounting of the coil array 14.
