A superconducting tunable filter is disclosed that has a center frequency and a bandwidth able to be adjusted separately. The superconducting tunable filter includes a superconducting resonator filter pattern formed on a dielectric substrate; a dielectric or magnetic plate above the resonator filter pattern and having a through-hole; a dielectric or magnetic rod inserted in the through-hole; and a position controller which separately controls the position of the dielectric or magnetic plate and the position of the dielectric or magnetic rod relative to the resonator filter pattern.
