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, internal electrodes disposed between the ceramic layers, a main surface oriented in the first direction, a surface layer portion in a range from the main surface to a predetermined depth, and a center portion adjacent to the surface layer portion in the first direction. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction. The ceramic layers have an average dimension in the first direction that is 0.4 ?m or less. Each of the internal electrodes includes an oxidized region adjacent to the side margin. The oxidized region in the surface layer portion has 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.

Abstract: A multi-layer ceramic capacitor includes a body including a multi-layer unit and a side margin, and an external electrode. The multi-layer unit includes ceramic layers laminated in a first direction, first and second internal electrodes alternately disposed between the ceramic layers, an end surface oriented in a second direction orthogonal to the first direction, the first internal electrode being drawn from the end surface, an end margin disposed between the end surface and the second internal electrode, and a side surface oriented in a third direction orthogonal to the former directions, the internal electrodes being exposed to the side surface. The side margin covers the side surface. The external electrode includes an entry portion and covers the body from the side of the end surface, the entry portion being disposed on the end margin and entering a gap between the side surface and the side margin from the end surface.
