Abstract
Official abstract text for this publication.
A multi-layer ceramic capacitor includes a multi-layer unit, a side margin, and a bonding unit. The multi-layer unit includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers and mainly containing nickel. The side margin covers the multi-layer unit from a second direction orthogonal to the first direction. The bonding unit is disposed between the multi-layer unit and the side margin and has a higher concentration of magnesium than the ceramic layers and the side margin.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-layer ceramic capacitor, comprising: a multi-layer unit that includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers and mainly containing nickel; a side margin that covers the multi-layer unit from a second direction orthogonal to the first direction; and a bonding unit that is disposed between the multi-layer unit and the side margin and has a higher concentration of magnesium than the ceramic layers and the side margin, wherein a center portion of the side margin in the second direction has a higher concentration of magnesium than center portions of the ceramic layers in the second direction. 2. A multi-layer ceramic capacitor, comprising: a multi-layer unit that includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers and mainly containing nickel; a side margin that covers the multi-layer unit from a second direction orthogonal to the first direction; and a bonding unit that is disposed between the multi-layer unit and the side margin and has a higher concentration of magnesium than the ceramic layers and the side margin, wherein each of the internal electrodes includes an oxidized region, the oxidized region being adjacent to the bonding unit and containing nickel and magnesium, and wherein a center portion of the side margin in the second direction has a higher concentration of magnesium than center portions of the ceramic layers in the second direction. 3. A multi-layer ceramic capacitor, comprising: a multi-layer unit that includes ceramic layers laminated in a first direction, and internal electrodes disposed between the ceramic layers and mainly containing nickel; a side margin that covers the multi-layer unit from a second direction orthogonal to the first direction; and a bonding unit that is disposed between the multi-layer unit and the side margin and has a higher concentration of magnesium than the ceramic layers and the side margin, wherein a region adjacent to the bonding unit in the ceramic layers has a higher concentration of magnesium than center portions of the ceramic layers in the second direction. 4. The multi-layer ceramic capacitor according to claim 3 , wherein the concentration of magnesium in the ceramic layers and the side margin increases toward the bonding unit.
