Abstract:
1. A multilayer ceramic capacitor comprising: a ceramic base body comprising primary phase particles comprising a CaZrO3-based compound as a primary component and secondary phase particles containing at least Mn; internal electrodes primarily composed of Cu embedded in the ceramic base body; and a pair of external electrodes at external portions of the ceramic base body each of which is electrically connected to a different internal electrode, wherein the ceramic base body contains about 2 parts by mole or more of Mn and about 0.69 parts by mole or more of Si relative to 100 parts by mole of the primary component, and the area ratio of the secondary phase particles on a cross-section of the ceramic base body is about 0.1% or more, and wherein secondary phase particles comprise particles having a particle diameter of at least about 0.1 μm and about 67% or more of the secondary phase particles having a particle diameter of about 0.1 μm or more contain Cu and Si.
