Abstract
A multilayer ceramic capacitor that includes a ceramic laminated body having dielectric layers and internal electrodes at the interfaces between the dielectric layers, and external electrodes on the outer surface of the ceramic laminated body. The dielectric layers contain, as their main constituent, a perovskite-type compound including Ba, Ti, Zr, and M. M is at least one element of Ta, Nb, V, and W. The dielectric layers further contain Mn and Si as additive constituents. With respect to the total amount of Ti, Zr, and M, 40 mol %<Zr≤90 mol %, M is 1 mol %≤M≤10 mol %. When the total amount of Ti, Zr, and M is regarded as 100 parts by mol, 1 part by mol≤Mn≤10 parts by mol, 1 part by mol≤Si≤5 parts by mol, and 0.5≤Mn/M≤3.0.
