ABSTRACT:
A perovskite oxide is represented by a general formula ABO3A represents at least one kind of metal element forming an A site, B represents at least one kind of metal element forming a B site. The B site includes at least one kind of metal element B1 selected from an element group consisting of the IV group elements and at least one kind of metal element B2 selected from an element group consisting of the V and VI group elements, and at least a part of the metal element B2 is of the 0 to +4 valence.
