Multilayer ceramic capacitor and method of manufacturing the same
Abstract:
A multilayer ceramic capacitor includes a multilayer body including a plurality of stacked dielectric layers including a dielectric ceramic that includes a plurality of crystal grains and a plurality of internal electrodes disposed at a plurality of interfaces between the dielectric layers, and external electrodes. The multilayer body includes a Ba and Ti containing perovskite compound, La, Mg, Mn and Al, and satisfies conditions such that in a case in which a content of Ti is set to 100 molar parts, a fraction of each content of La, Mg, Mn and Al relative to the content of Ti is such that La is about 0.2 to about 1.2 molar parts, Mg is about 0.1 molar part or less, Mn is about 1.0 to about 3.0 molar parts and Al is about 0.5 to about 2.5 molar parts, and an average number of crystal grains included in each of the dielectric layers in the stacking direction is one or more to three or less.
