Abstract
The present invention provides a Bi2223 based thick film that does not peel off when a thermal or a mechanical shock is applied to a base or an oxide superconductor thick film or the like in the middle of a manufacturing process and a method of manufacturing the same. An oxide superconductor pastehaving a mixing ratio of Bi2212 composition is applied to a basedried, burned, and thereafter burned at a temperature approximate to its melting point to obtain a partially molten layer. Next, an oxide superconductor pastehaving a mixing ratio of Bi2223 composition is applied to the partially molten layer, dried, burned, compressed by a CIP, and thereafter repeatedly burned and compressed for a predetermined number of times to obtain the basehaving a desired superconductor thick filmformed thereon.
