Zusammenfassung:	To provide a perovskite type composite oxide from which a dense sintered body can be obtained even by calcining the same at a relatively low temperature in an atmospheric environment, and a method of producing the same.SOLUTION: A perovskite type composite oxide is produced by calcining a solid matter obtained by neutralizing an acid solution containing a starting material of a perovskite type composite oxide represented by composition formula BaZr1-x-yCexMyO3 (M is at least one element selected from the group consisting of Y, Yb, Sc and Tm, 0≤x≤0.7, and 0
