Abstract
On a first intermediate layer provided on a substrate and having an excellent surface smoothness, are formed a second intermediate layer and an YBCO superconductor layer having excellent properties. An YBCO superconductor () having a critical current density (Jc) of 1 MA/cmor higher can be produced by forming a first intermediate layer (), a second intermediate layer (), an YBCO superconductor layer () and an Ag-stabilized layer () on the surface of a tape-shaped biaxially oriented Ni—W alloy substrate (), wherein the first intermediate layer () has a thickness of 5 nm or less, has a surface smoothness, comprises AZrO, and is formed by repeating coating and provisional burning several times by the MOD method, the second intermediate layer () comprises a CeOfilm and is formed by the pulse plating method, the YBCO superconductor layer () is formed by the MOD method, and the Ag-stabilized layer () is formed on the YBCO superconductor layer ().
