Claim Text:
1. A multilayer ceramic capacitor comprising a multilayer body having a plurality of laminated dielectric ceramic layers and a plurality of internal electrodes at different interfaces between said dielectric ceramic layers; and external electrodes on an outer surface of said multilayer body, wherein a dielectric ceramic comprising the dielectric ceramic layers comprises a perovskite-type compound containing Ba and Ti as a primary ingredient, and the dielectric ceramic further includes Bi and one of M and Q as sub-ingredients, in which M is at least one member of the group consisting of Cu, Zn, Li, K, and Na, and Q is at least one member of the group consisting of Ba, Ca and Sr, a total content of M, Q and Bi is equal to or greater than 3 molar parts when a total content of Ti is 100 molar parts, and a crystal particle size of said dielectric ceramic is 30 nm or more and 150 nm or less.
