A ceramic capacitor comprising:
- a multilayer structure in which each of a plurality of dielectric layers and each of a plurality of internal electrode layers are alternately stacked,
- wherein a main component of the plurality of dielectric layers is BaTiO3,
- wherein the plurality of dielectric layers include 0.05 atm % or more and 0.35 atm % or less of Mn as a first sub-component, 0.4 atm % or more and 0.8 atm % or less of Mg as a second sub-component, 0.5 atm % or more and 0.9 atm % or less of a rare earth element which is at least one of Ho and Dy as a third sub-component, 0.15 atm % or more and 0.30 atm % or less of V as a fourth sub-component, 0.4 atm % or more and 0.9 atm % or less of Si as a fifth sub-component, 0.00 atm % or more and 0.45 atm % or less of Ca as a sixth sub-component, on a presumption that an amount of Ti of the main component is 100 atm %,
