Abstract
Official abstract text for this publication.
A multi-layer ceramic capacitor includes: a multi-layer unit including a capacitance forming unit including internal electrodes laminated in a first direction, a drawn portion extending from the capacitance forming unit in a second direction, and a cover that covers the capacitance forming unit and the drawn portion in the first direction, the multi-layer unit having a main surface facing in the first direction, an end surface facing in the second direction, and a side surface facing in a third direction; and a side margin provided to the side surface, the side surface including a first straight portion including an outer edge of the main surface and extending in the second direction, a second straight portion including an outer edge of the end surface and extending in the first direction, and a corner portion that connects the first and second straight portions with each other, the corner portion being curved.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-layer ceramic capacitor, comprising: a multi-layer unit including a capacitance forming unit that includes internal electrodes laminated in a first direction, a drawn portion that extends from the capacitance forming unit in a second direction orthogonal to the first direction, the internal electrodes being drawn in the drawn portion, and a cover that covers the capacitance forming unit and the drawn portion in the first direction, the multi-layer unit having a main surface facing in the first direction, an end surface facing in the second direction, and a side surface facing in a third direction orthogonal to the first direction and the second direction; and a side margin provided to the side surface, the side surface including a first straight portion that includes an outer edge of the main surface and extends in the second direction, a second straight portion that includes an outer edge of the end surface and extends in the first direction, and a corner portion that connects the first straight portion and the second straight portion with each other, the corner portion being curved to satisfy conditions where 0.4≤a/b≤2.5, and 10 μm≤a, b≤60 μm, where a represents a distance along the first direction between a first imaginary line extended from the first straight portion in the second direction and an endpoint of the second straight portion on a side of the first imaginary line, and b represents a distance along the second direction between a second imaginary line extended from the second straight portion in the first direction and an end portion of the drawn portion, the end portion being exposed from the side surface and positioned at a boundary between the capacitance forming unit and the cover. 2. The multi-layer ceramic capacitor according to claim 1 , wherein the corner portion is curved to further satisfy a condition where 0.5≤a/b≤1.5. 3. The multi-layer ceramic capacitor according to claim 1 , wherein the corner portion is curved to further satisfy conditions where 1.0≤a/b≤1.5, and 10 μm≤b≤30 μm.
