A superconductor arrangement (100) comprises an oxide superconducting layer (30) including at least first and second superconducting regions (31) containing barium, copper, and a rare earth element, having a continuous perovskite structure and extending in a first direction, and a non-superconducting region (32) disposed between the superconducting regions, containing praseodymium, barium, copper, and a rare earth element, wherein a ratio of the number of the praseodymium atoms to a sum of the number of the rare earth element and praseodymium atoms is 20% or more, having a continuous perovskite structure continuous with the perovskite structure of the superconducting regions, and extending in the first direction. A corresponding manufacturing method using sol-gel deposition is disclosed as well.
