Abstract
A dielectric ceramic contains a barium titanate and Li. In the dielectric ceramic, the following inequalities are satisfied: 0.5≦e≦6.0, 0.06<Rg<0.17, and σg<0.075, where e is the content, in molar parts, of Li with respect to 100 molar parts of the titanate; Rg is the average size, in μm, of grains in the dielectric ceramic; and σg is the standard deviation, in μm, of the size of the grains.
