PROBLEM TO BE SOLVED: To provide a compact and characteristic control-enabled superconducting filter unit with a plurality of resonance purposes elements placed in multi-stage. SOLUTION: The superconducting filter unit includes: a plurality of resonance purposes elements (23a, 23b) having a superconducting resonant pattern (66) on a dielectric substrate; an input port (102) for supplying signals to the resonance purposes elements and an output port (103) for retrieving the signals from the resonance purposes elements; and substrate-like joint purposes elements (22a-22c) placed between the adjacent resonance purposes elements, between the resonance purposes element and the input port, or between the resonance purposes element and the output port. Further, the resonance purposes elements and the joint purposes elements are placed such that they can be replaced in a direction perpendicular to the resonant patterns.
