Abstract
A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrode layers, and external electrodes. The multilayer body includes side margin portions made of a dielectric. In the internal electrode layers, a width of an extension electrode portion is smaller than a width of a counter electrode portion. The side margin portions each include Ba and Ti as a main component and Mg as a sub component. The Mg content is about 0.2 mol % or more and about 2.0 mol % or less with respect to 100 mol of Ti. The internal electrode layers each include Ni as a main component, and an end portion of the counter electrode portion includes Mg as a sub component. The Mg content is about 0.13 mol % or more and about 0.39 mol % or less with respect to 100 mol of Ni.
