PROBLEM TO BE SOLVED: To provide a dielectric filter, in which conductivity deterioration caused by heat cycle or others between a circuit board and a coupling board is prevented so that a stabilized characteristic of the filter is secured for a long time. SOLUTION: The dielectric filter comprises a circuit board 1, a coupling board 3 mounted on the circuit board 1, a terminal connecting the circuit board 1 and the coupling board 3, and a resonator 5 electrically connected to the coupling board 3. The terminal 8 consists of elastic material, and has a connection 8a and 8b, and an elastic part 8c provided between the connections 8a and 8b.
