Abstract

A superconductive element at least comprising first and second superconductive electrodes composed of an oxide superconductor material and a semiconductor film composed of an oxide semiconductor material put between the first and second superconductive electrodes and disposed in adjacent with the first and the second superconductive electrodes, in which the semiconductor film is formed with an oxide comprising rare earth elements other than Pr, Ba and Cu as the main ingredient element or an oxide comprising predetermined amount of rare earth elements other than Pr, predetermined amount of Pr, Ba and Cu as the main ingredient element. Extremely fine size is no more necessary to enable fabrication with the existent fine fabrication technic.
