Multilayer ceramic capacitor

A multilayer ceramic capacitor comprising:

• a pair of external electrodes;
• a first internal electrode that contains a base metal and is coupled to one of the pair of external electrodes;
• a dielectric layer that is stacked on the first internal electrode and contains the base metal and a ceramic material mainly composed of barium titanate;
• and
• a second internal electrode that is stacked on the dielectric layer, contains the base metal, and is coupled to another one of the pair of 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 internal electrode and the second internal electrode equally into five, and
• an atomic concentration ratio of Mg to Ti is equal to or greater than 0 and less than 0.002 in the dielectric layer.
