Abstract
A multi-layer ceramic electronic component includes a plurality of layered internal electrodes and a first crystal grain. The plurality of layered internal electrodes are disposed at intervals in a first direction and each include a pore. The first crystal grain has a larger diameter in the first direction than the interval and has a part disposed in the pore.
Claims8
A multi-layer ceramic electronic component, comprising:
- a plurality of layered internal electrodes that are disposed at intervals in a first direction, each internal electrode of the plurality of layered internal electrodes including a pore penetrating through the respective internal electrode in the first direction;
- a side margin that covers the plurality of layered internal electrodes in a second direction orthogonal to the first direction;
- and
- a first crystal grain existing at a boundary portion between the plurality of layered internal electrodes and the side margin, the first crystal grain having a larger diameter in the first direction than the interval and having a part disposed in the pore of a first internal electrode of the plurality of layered internal electrodes,
- wherein each layered internal electrode of the plurality of layered internal electrodes comprises an end portion and extends in the second direction to its respective end portion, and
- wherein the end portions of the layered internal electrodes are aligned with each other in the first direction.
