Abstract
A multilayer ceramic capacitor that includes a laminate which has a plurality of dielectric layers and a plurality of internal electrode layers respectively laminated. The dielectric layers are a perovskite type structure containing Ba, Sr, Zr, Ti and Hf, and optionally Ca, and further include V, wherein (number of moles of Sr)/(number of moles of Ba+number of moles of Ca+number of moles of Sr) is 0.6 to 0.95, (number of moles of Zr)/(number of moles of Zr+number of moles of Ti+number of moles of Hf) is 0.9 to 0.98, thicknesses of the dielectric layers are 1 μm or less, and an average particle size of dielectric particles constituting the dielectric layers is 0.8 μm or less.
