The Re oxide films were deposited on quartz glasses by RF reactive sputtering from a Re metal target. The lowest resistivity was observed in the film in-situ annealed at 200°C in Ar atmosphere and showed the order of 10-4 [ cm of which the value was still about 10 times as large as that of a single crystal ReO 3 . The temperature dependence of the resistivity revealed a metallic behavior. A superconductivity did not take place in the bilayered film of ReO 3 / NdBa 2 Cu 3 0 6 . In the interface
