Abstract

PURPOSE:To obtain a superconductor element which can perform a stable operation for a long time without any fatigue due to thermal strain by a method wherein a polycrystalline oxide superconductor layer which has a narrowed region is formed on an insulating substrate, and the narrowed region is used as a current squeezing region and the flat regions of both sides between which the former is placed are used as the first and second electrode. CONSTITUTION:By a sputtering process performed on an insulating substrate 31 consisting of sapphire or the like in an atmosphere which contains Ar and O2 maintaining at the temperature of approximately 250 deg.C and using a Ba1.5Pb0.75 Bi0.25O3 ceramic plate as a target, a strip of polycrystalline oxide superconductor layer 33 having a requested shape is obtained. Namely a superconductor layer 33 consisting of BaPb0.75Bi0.25O3 having a narrowed region 32 which has a width of approximately 20mum and a length around 10mum, and a flat region 34, 35 at its both sides having a width around 50mum and a thickness around 5000Angstrom is formed. In this cnstitution the narrowed region 32 is used as the current contracted region 38 and flat regions 34 and 35 are used as electrode regions 36 and 37.
