Abstract
A superconductive magnetoresistor has a substrate, a ceramic superconductive film which is formed on one face of the substrate, ferromagnetic elements for focusing an external magnetic field, and an insulating film. One of the ferromagnetic elements is integrally combined with the other face of the substrate. The other of the ferromagnetic elements is combined with the ceramic superconductive film thorough the insulating film.
