Abstract: A method of producing a superconductor of metal oxides which includes subjecting an organic solvent solution containing (a) an alkoxide of a rare earth element, (b) an alkoxide of an alkaline earth metal and (c) copper alkoxide or cupric nitrate to hydrolysis in the presence of water and nitrate ions, thereby forming a mixture containing a gel-like substance. The gel-like substance is, after being dried and formed into a desired shape, pyrolyzed at a temperature of 600.degree.-950.degree.C. to form a superconductor of oxides of the rare earth, the alkaline earth metal and copper.
