Multi-layer ceramic capacitor and method of producing the same
A multi-layer ceramic capacitor includes a body. The body includes a capacitance forming unit, a cover, and a side margin. The capacitance forming unit includes ceramic layers laminated in a first direction and internal electrodes disposed between the ceramic layers. The cover covers the capacitance forming unit from the first direction. The side margin covers the capacitance forming unit from a second direction orthogonal to the first direction. The capacitance forming unit includes a surface layer portion adjacent to the cover. Ends of the internal electrodes in the second direction in the surface layer portion are curved toward the cover.
1. A multi-layer ceramic capacitor, comprising:
a body including:
a main surface oriented in a first direction and being a flat surface;
a capacitance forming unit that includes ceramic layers laminated in the first direction and internal electrodes disposed between the ceramic layers;
a cover that covers the capacitance forming unit from the first direction; and
a side margin that covers the capacitance forming unit from a second direction orthogonal to the first direction,
the capacitance forming unit including a surface layer portion adjacent to the cover,
ends of the internal electrodes in the second direction in the surface layer portion being curved toward the cover, and
in an internal electrode adjacent to the cover, a distance in the first direction between the main surface and the end of the internal electrode being shorter than a distance in the first direction between the main surface and the center portion of the internal electrode in the second direction.
2. The multi-layer ceramic capacitor according to claim 1 , wherein
a dimension of a portion of the surface layer portion in the first direction is 5 μm or more, the ends of the internal electrodes being disposed in the portion.
