Claim:
1. A multilayer ceramic capacitor comprising: a ceramic body including a first end surface and a second end surface opposite to the first end surface, a first side surface and a second side surface perpendicular or substantially perpendicular to the first end surface and the second end surface, and a first major surface and a second major surface perpendicular or substantially perpendicular to the first end surface and the first side surface, and including a plurality of dielectric ceramic layers of a perovskite-type compound containing Ba and Ti, and internal electrode layers stacked on one another in a direction extending from the first major surface to the second major surface with a respective one of the plurality of dielectric ceramic layer between each adjacent pair of the internal electrodes; and external electrodes provided on the ceramic body at the first end surface and the second end surface, respectively; wherein the internal electrodes includes a first internal electrode and a second internal electrode; each of the first internal electrode and the second internal electrode extends out to a respective one of the first end surface and the second end surface, and is electrically connected to a respective one of the external electrodes; when the ceramic body is seen in a direction in which the layers are stacked, the ceramic body includes a region free of the first internal electrode and the second internal electrode defining a side margin portion; and the side margin portion includes ceramic grains of the ceramic dielectric with Ba between the ceramic grains; and an amount of the Ba decreases along a direction extending from inside to outside of the ceramic body.
