Abstract
A multi-layer ceramic capacitor includes a multi-layer unit and a side margin. The multi-layer unit includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction, the side margin having a higher concentration of a rare-earth element and a higher concentration of vanadium than center portions of the ceramic layers in the second direction.
