Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A multi-layer ceramic capacitor, comprising: a body including a multi-layer unit including ceramic layers laminated in a first direction, a first internal electrode and a second internal electrode that are alternately disposed between the ceramic layers, an end surface that is oriented in a second direction orthogonal to the first direction, the first internal electrode being drawn from the end surface, an end margin that is disposed between the end surface and the second internal electrode, and a side surface that is oriented in a third direction orthogonal to the first direction and the second direction, the first internal electrode and the second internal electrode being exposed to the side surface, and a side margin that covers the side surface of the multi-layer unit; and an external electrode that includes an entry portion and covers the body from a side of the end surface, the entry portion being disposed on the end margin, the entry portion entering a gap, between the side surface and the side margin, from the end surface, the entry portion projecting outward from the side surface towards the side margin, the entry portion being in direct physical contact with the side surface, and the side surface being absent in the side margin. 2. The multi-layer ceramic capacitor according to claim 1 , wherein a dimension of the entry portion in the second direction is 30% or less of a dimension of the end margin in the second direction. 3. The multi-layer ceramic capacitor according to claim 1 , wherein the entry portion is provided over an entire width of the end margin in the first direction between the side margin and the side surface. 4. The multi-layer ceramic capacitor according to claim 2 , wherein the entry portion is provided over an entire width of the end margin in the first direction between the side margin and the side surface. 5. The multi-layer ceramic capacitor according to claim 1 , wherein the entry portion is provided in plurality and the entry portions are provided separately from one another in the first direction between the side margin and the side surface. 6. The multi-layer ceramic capacitor according to claim 2 , wherein the entry portion is provided in plurality and the entry portions are provided separately from one another in the first direction between the side margin and the side surface.
