Abstract
A superconductive filter includes a superconductive filter substrate having a dielectric substrate and a plurality of resonator patterns formed on a surface of the dielectric substrate, the plurality of resonator patterns including a superconductive material; a package accommodating the superconductive filter substrate; and an intermediate substrate disposed between an inner surface of the package and the superconductive filter substrate, and thermally coupling the package and the superconductive filter substrate wherein a difference between a degree of contraction of the intermediate substrate and the degree of contraction of the dielectric substrate is smaller than a difference between the degree of contraction of the dielectric substrate and the degree of contraction of the package, when the package, the intermediate substrate, and the dielectric substrate are cooled from room temperature to a critical temperature of the resonator patterns.
