摘要： This invention provides a tape-shaped oxide superconductor which can prevent the diffusion of elements constituting a metallic substrate into a superconducting layer and cracking of an intermediate layer and improve the orientation of the superconducting layer. A 15 to 100 nm-thick Ce—Gd—O-based oxide layer (2) (Ce:Gd=40:60 to 70:30 molar ratio) as a first intermediate layer and a 100 nm-thick Ce—Zr—O-based oxide layer (3) (Ce:Zr=50:50 molar ratio) as a second intermediate layer are formed by an MOD method on an Ni-base alloy substrate (1) having a half value width (FMHW: Δφ) of 6.5 degrees. A 150 nm-thick CeO2 oxide layer (4) as a third intermediate layer is further formed on the second intermediate layer by an RF sputtering method. A 1 μm-thick YBCO superconducting layer (5) is formed by a TFA-MOD method on the intermediate layer having a three-layer structure. In the tape-shaped oxide superconductor, the Δφ values of the first to third intermediate layers are (6.0 to 6.5) degrees, (6.0 to 6.6) degrees, and (6.0 to 6.6) degrees, respectively, and the Jc value of the YBCO superconducting layer (5) in liquid nitrogen is 1.8 to 2.2 MA/cm2.
