Claim:
1. A complex oxide comprising: a chemical compound represented by ABO a chemical compound represented by BaB wherein in the Chemical Formula 1, A is one or more elements selected from Ba, Ca, and Sr; and B is one or more elements selected from Ti, Zr, Hf, and Sn, and in the Chemical Formula 2, B is one or more elements selected from Ti, Zr, Hf, and Sn, wherein the chemical compound represented by the Chemical Formula 2 is included in the chemical compound represented by the Chemical Formula 1, so that a ratio of an amount of the chemical compound represented by the Chemical Formula 2 with respect to that of the chemical compound represented by the Chemical Formula 1 is greater than or equal to 0.5 mol % and less than or equal to 3 mol %, and wherein, when a field having a size of 1 μm×1 μm on a surface of the complex oxide is observed with an atomic force microscope (AFM), a typical particle size is greater than or equal to 300 nm and less than 660 nm, wherein the typical particle size is a maximum length of a maximum particle observed in the field.
