Abstract
A ceramic capacitor having dielectric ceramic layers that include Ba, Re (Re is at least one of La, Ce, Pr, Nd, and Sm), Ti, Zr, M (M is at least one of Mg, Al, Mn, and V), Si, and optionally Sr, where at least some of the Ba, Re, Ti, and Zr and optionally Sr are in the form of a perovskite compound. Respective amounts, expressed as parts by mol, of the elements of the dielectric ceramic layers satisfy, with respect to a total of 100 of the Ti amount and the Zr amount, 0≦a≦20.0 where a is the Sr amount; 0.5≦b≦10.0 where b is the Re amount; 46≦c≦90 where c is the Zr amount; 0.5≦d≦10.0 where d is the M amount; 0.5≦e≦5.0 where e is the Si amount; and 0.990≦m≦1.050 where m is a ratio of a total of the Ba amount, the Sr amount, and the Re amount, to the total of the Ti amount and the Zr amount.
