Abstract

PURPOSE:To obtain an element which is stable for a long time by a method wherein on an insulative substrate, a polycrystalline oxide superconductor layer consisting of BaPbBiO is applied and covered with an insulation layer, and a window in corespondence with a current squeezing region is bored, and a superconductor layer of the same kind of the upper layer which comes in contact with the super conductor layer through the window is provided all over the surface. CONSTITUTION:On an insulative substrate 31 consisting of sapphire or the like a polycrystalline oxide superconductor layer 32 of BaPb0.75Bi0.25O3 is attached and it is covered all over its surface with an insulating layer 34 such as Al2O3 or Si2O2 or the like. Next, a window 33 is bored at the center on the insulating layer 34, a region of the super conductor layer 32 is exposed, and contacted with it polycrystalline oxide superconductor layer 35 of the same kind is formed on the insulating layer 34. Subsequently an insulating layer 41 is applied all over it, and a superconductor layer 42 for control is attached on the layer 41 in corespondence with the layer 37 in the superconductor layer 35 placed within the window 33. By this method by using a region of the layer 37 as a current squeezing region 40, a superconductor without thermal strain is obtained.
