摘要： 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 μm 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.
