Abstract
A complex oxide includes a chemical compound represented by ABO(Chemical Formula 1). 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. 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. Here, the typical particle size is a maximum length of a maximum particle observed in the field.
