That is, in the conventional method, oxygen is released from the oxide superconductor during the formation of the thin film, and the superconductivity of the thin film becomes insufficient. Therefore, a heat treatment in an oxygen atmosphere is essential. Excited oxygen is supplied to the deposition portion or its vicinity during deposition, so that a sufficient amount of oxygen is taken into the thin film, and good superconductivity can be obtained without performing heat treatment in an oxygen atmosphere. And can be.
