Zusammenfassung:PURPOSE:To obtain a substrate for superconducting microwave devices using an oxide superconducting thin film. CONSTITUTION:The subject substrate is a substrate for microwaves having a ground substrate, the first oxide superconductor layer, a dielectric layer and the second oxide superconductor layer successively laminated on the aforementioned ground substrate. The aforementioned dielectric layer is formed from a double oxide thin film of La, Ca and Mn having a perovskite type crystal structure.
