ABSTRACT:
A dielectric ceramic includes a compound represented by the general formula: (Ba1-tCat)m(Ti1-u-xZruCux)O3(where 0.96≦m≦1.02, 0.001≦x≦0.03, 0≦t≦0.1, and 0≦u≦0.06) as a primary component, a rare earth element Re such as Dy, a metal element M such as Mn, Mg, and Si. In the dielectric ceramic, the Cu is uniformly and dispersedly present in the primary phase grain forming the primary component, and the contents of the accessory components with respect to 100 molar parts of the primary component are 0.1 to 1.5 molar parts of Re, 0.1 to 0.6 molar parts of M, 0.1 to 1.5 molar parts of Mg and 0.1 to 2.0 molar parts of Si. Accordingly, a multilayer ceramic capacitor can be realized which has a high dielectric constant, superior temperature properties, and a high reliability, and also has a small change in electrostatic capacitance with time.
