Abstract

PURPOSE:To alleviate the concentration of currents, and to elevate the upper limit of superconductive currents capable of being flowed while maintaining superconductivity by forming a normal conductive film having resistivity higher than a normal conductive film or a tunnel barrier film between a superconductive film and the normal conductive film. CONSTITUTION:A contact section is composed of a Nb film 4 as a superconductive film in a sectional drawing, an SiO2 film 5, an Al oxide film 6 and an Al resistance film 7. Contact resistance between the Nb film 4 and the Al resistance film 7 is increased in the presence of the Al oxide film. The Al resistance film 7 just under a contacting section is thickened, thus lowering surface resistance. Accordingly, currents flowing through the contact are dispersed, and the upper limit of currents capable of being flowed through a superconductive line including the contact without breaking superconductivity is elevated.
