Abstract

PURPOSE:To realize a superconductive circuit board which is superb in coherency and does not produce cracks and peeling even if cooling/heating cycle is repeated by forming an oxide superconductive layer on a metal conductive layer which is formed on a ceramic substrate. CONSTITUTION:A metal conductive layer 2 consisting of copper is formed by performing plasma flame spraying of copper powder onto sand blast processed surface of a nitrided aluminum substrate 1 in argon gas atmosphere through a masking plate 4. Then, plasma flame spraying is performed on the metal conductive layer 2 in argon gas atmosphere through the masking plate 4 using oxide superconductive powder to form a oxide superconductive layer 3 and to obtain the desired superconductive circuit board. A metal conductive layer between a ceramic substrate and oxide superconductive layer prevents the generation of heat stress due to difference in heat expansion coefficients between the oxide superconductive layer and ceramic substrate, enhances coupling strength, and improves reliability for cooling/heating cycle.
