Abstract

Official abstract text for this publication.

A multi-layer ceramic electronic component 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 that faces in the first direction, and a side surface that faces in a second direction orthogonal to the first direction, the internal electrodes being exposed from the side surface. The side margin includes a side-surface-covering portion that is disposed on the side surface, and an end portion that includes an extended portion extending from the side surface to the main surface and having a first dimension of 0.1 μm or more in the first direction and a second dimension of 0.1 μm or more in the second direction.

First claim

Opening claim text (preview).

What is claimed is: 1. A multi-layer ceramic electronic component, comprising a multi-layer unit including ceramic layers laminated in a first direction, internal electrodes disposed between the ceramic layers, a main surface that faces in the first direction, and a side surface that faces in a second direction orthogonal to the first direction, the internal electrodes being exposed from the side surface; and a side margin including a side-surface-covering portion that is disposed on the side surface, and an end portion that includes an extended portion extending from the side surface to the main surface and having a first dimension of 0.1 μm or more in the first direction and a second dimension of 0.1 μm or more in the second direction, wherein the first dimension is 3 μm or less, and wherein the second dimension is 10 μm or less. 2. The multi-layer ceramic electronic component according to claim 1 , wherein the second dimension is 5 μm or more. 3. The multi-layer ceramic electronic component according to claim 1 , wherein the first dimension is 0.5 μm or more, and the second dimension is 1 μm or more. 4. The multi-layer ceramic electronic component according to claim 1 , wherein the side-surface-covering portion has a dimension of 10 μm or more in the second direction, and the side-surface-covering portion has a porosity of 10% or less. 5. The multi-layer ceramic electronic component according to claim 4 , wherein the end portion has a porosity lower than the porosity of the side-surface-covering portion.
