Abstract
An object of the invention is to provide: an MgBsuperconducting thin-film wire that exhibits excellent Jcharacteristics even under a 20 K magnetic field; and a method for producing thereof. The MgBsuperconducting thin-film wire includes a long substrate and an MgBthin film formed on the long substrate. The MgBthin film has a microtexture such that MgBcolumnar crystal grains stand densely together on the surface of the long substrate, and has Tof 30 K or higher. In grain boundary regions of the MgBcolumnar crystal grains, a predetermined transition metal element is dispersed and segregated. The predetermined transition metal element is an element having a body-centered cubic lattice structure.
