Abstract
An oxide superconductor thin film of Y.sub.1.+-..alpha. Ba.sub.2.+-..beta. Cu.sub.3.+-..gamma. O.sub.7-.delta. with a smooth surface having a low density of particles being generated without decreasing superconductivity is produced by the steps of applying a pulsed laser beam to the target formed of an oxide material having an apparent density of 95% or more, substantially composed of Y.sub.1.+-..alpha. Ba.sub.2.+-..beta. Cu.sub.3.+-..gamma. O.sub.7-.delta., which is obtained from a molded body of an amorphous powder by subjecting it to partial melting, followed by gradual cooling, depositing and accumulating an irradiated and evaporated oxide material of the target on a substrate.
