PROBLEM TO BE SOLVED: To miniaturize a dielectric filter available at a high frequency band. SOLUTION: In this dielectric filter, two resonators are arranged in a longitudinal direction in a rectangular parallelepiped dielectric body 11, and island- shaped conductor films 13 and 14 are interdigitally formed on one surface of the dielectric body as input and output electrodes. Any conductor film is not formed in parts in contact with the island-shaped conductor films, but a conductor film 15 is formed in the other parts as ground electrodes, and one part of the dielectric body between the input and output electrodes is removed so that the connection can be adjusted.
