An oxide superconducting wire of the invention includes a substrate (1, 11, 21, 31, 41, 51), an intermediate layer (2, 12, 22, 32, 42, 52) which is laminated on a main surface of the substrate, has one or more layers having an orientation, and has one or more non-orientation regions (2b, 3b, 12b, 13b, 22b, 23b, 32b, 33b, 43b, 52b, 53b) extending in a longitudinal direction of the wire, and an oxide superconducting layer (3, 13, 23, 33, 43, 53) which is laminated on the intermediate layer, has a crystal orientation controlled by the intermediate layer, and has non-orientation regions located on the non-orientation regions in the intermediate layer and is formed into multiple filaments.
