摘要： An oxide superconductor having a composition of the formula: A.sub.n+1 Cu.sub.n O.sub.2n+1+.delta. in which A is at least one alkaline earth metal element selected from the group consisting of calcium, strontium and barium, n is an integer of at least one, and .delta. is a number larger than 0 and not larger than 1, a laminate structure in which a layer having a partial composition of A.sub.2 O.sub.1+.delta. and a layer having a partial composition of A.sub.n-1 Cu.sub.n O.sub.2n are alternately laminated, and a superconductive critical temperature equal to or higher than the liquid nitrogen temperature.
