Multi-layer ceramic capacitor

A multi-layer ceramic capacitor, comprising:

• a multi-layer unit that includes
• ceramic layers laminated in a first direction,
• internal electrodes disposed between the ceramic layers,
• a main surface facing the first direction,
• a side surface facing a second direction orthogonal to the first direction,
• a surface layer portion in a range from the main surface to a predetermined depth, the surface layer portion having a cover portion including the main surface, a first internal electrode in an outermost layer adjacent to the cover portion and included in the internal electrodes, and a second internal electrode separate from the first internal electrode and included in the internal electrodes, and
• a center portion adjacent to the surface layer portion in the first direction;
• and
• a side margin that covers the side surface of the multi-layer unit from the second direction, such that all internal electrodes are covered from the second direction by the side margin,
• each of the internal electrodes including an oxidized region that is adjacent to the side margin,
• the oxidized region of the second internal electrode in the surface layer portion having a dimension in the second direction that is equal to or more than two times the average dimension of the ceramic layers in the first direction, and
• the oxidized region of each of the internal electrodes in the center portion having a dimension in the second direction that is less than two times the average dimension of the ceramic layers in the first direction.
