A superconducting filter device is disclosed that includes a dielectric base substrate; a patch-type resonator pattern formed of a superconducting material on the base substrate; and a feeder extending in the vicinity of the resonator pattern. The feeder includes a transmission line part for signal inputting or signal outputting, the transmission line part extending toward the resonator pattern; a facing part bent from the transmission line part to face the resonator pattern; and an end part bent from the facing part in a direction away from the resonator pattern.
