A SQUID made of an oxide superconducting thin film is formed on a sapphire substrate. CeO2 film, RBa2Cu3O7-x film ("R" indicates a rare earth element chosen among a group formed of Yb, Er, Ho, Y, Dy, Gd, Eu, Sm and Nd) and SrTiO3 film are deposited on the substrate top of the sapphire substrate successively. Furthermore, an oxide superconducting thin film to form a SQUID is deposited on the SrTiO3 film.
