Abstract:
A multilayer ceramic capacitor includes: a pair of external electrodes; a first internal electrode containing a base metal and coupled to one of the external electrodes; a dielectric layer stacked on the first internal electrode and containing a ceramic material and the base metal; and a second internal electrode stacked on the dielectric layer, containing the base metal, and coupled to another one of the external electrodes, wherein a concentration of the base metal in each of five regions is within ±20% of an average of the concentrations of the base metal in the five regions, the five regions being obtained by dividing a region from a location 50 nm away from the first internal electrode of the dielectric layer to a location 50 nm away from the second internal electrode of the dielectric layer in a stacking direction between the first and second internal electrodes equally into five.
