Abstract

Provided is a novel compound which can be used for positive-electrode catalysts of metal-air batteries. The melilite-type complex oxide according to the present invention is represented by a general formula (BazSr1−z)2CoxFe2−2x(SiyGe1−y)1+xO7 (in the formula, 0≤x≤1, 0≤y≤1, and 0≤z≤1, excluding the case where x=1, y=1, and z=0, the case where x=1, y=1, and z=1, the case where x=1, y=0, and z=0, the case where x=1, y=0, and z=1, the case where x=0, y=0, and z=0, and the case where x=0, y=0, and z=1).
