Abstract
A multilayer ceramic capacitor () has a laminate body () constituted by dielectric layers () and internal electrode layers () stacked alternately. The dielectric layers () contain (BaCaSr)(TiZr)O, where 0.03≤x≤0.16, 0≤y≤0.02, 0<z≤0.02, 0.99≤m≤1.02, as a primary component, and an R oxide (R is a rare earth element) by 1.0 to 4.0 mol in equivalent element, an Mg compound by 0.2 to 2.5 mol in equivalent element, an Mn compound by 0.1 to 1.0 mol in equivalent element, a Zr compound by 0.1 to 2.0 mol in equivalent element, a V compound by 0.05 to 0.3 mol in equivalent element, and an Si compound by 0.2 to 5.0 mol in equivalent element, per 100 mol of the primary component. The multilayer ceramic capacitor can offer excellent DC bias properties and ensure high reliability.
