Abstract: Provided is a multilayer ceramic capacitor and a method of manufacturing the same. The multilayer ceramic capacitor includes a capacitor body including a dielectric layer and an internal electrode layer, and an external electrode disposed outside the capacitor body. The dielectric layer includes barium titanate-based main ingredient including barium (Ba) and titanium (Ti), and gallium (Ga)Peak intensity ratio of Ba/Ga (IBa/IGa), obtained by TEM-EDS analysis of a region from an interface between the dielectric layer and the internal electrode layer to a depth surface of 10 nm to 500 nm into the dielectric layer, is 1.0 to 5.0.
