<p>A laminated ceramic capacitor includes multiple dielectric layers, internal electrodes having Cu as the primary component and embedded between the dielectric layers, and external electrodes. The dielectric layers contain a primary component comprised of a CaZrO3 compound and auxiliary components that include Mn, B, Si, and Li wherein a primary phase comprised of the primary component, segregation phases containing Ca and at least one of the auxiliary components, and secondary phases containing at last Ca and Zr are formed. The ratio of Ca to Zr in the secondary phases is smaller than the ratio of Ca to Zr in the primary phase, and the number of secondary phases with a diameter of 100 nm or greater in a cross section of the dielectric layers averages 30 or less per 10 square mum.</p> |
