Abstract
An oxide superconductor wire including: an oxide superconductor laminate comprising: a tape-shaped substrate, an interlayer laminated on the substrate, an oxide superconductor layer laminated on the interlayer, and a protection layer which is formed of Ag or an Ag alloy and laminated on the oxide superconductor layer; and a stabilization layer which is formed of a metal tape and formed on the protection layer of the superconductor laminate via a low melting point metal layer, wherein the thickness of the protection layer is 5 μM or less, and wherein a volume resistivity of the stabilization layer at room temperature is no less than 3.8 μΩ·cm and no more than 15 μΩ·cm.
