Abstract

Disclosed are a method of manufacturing multilayer ceramic electronic components and a multilayer ceramic electronic component using the same. There is provided a method of preparing a plurality of ceramic layers including a first side, a second side, a third side, and a fourth side; printing a first inner electrode pattern and a second inner electrode pattern on the ceramic layers, the first inner electrode pattern and the second inner electrode pattern being exposed to the first side or the third side and having concave portions in the second side and fourth side directions; and stacking and compressing the plurality of ceramic layers printed with the first inner electrode pattern and the second inner electrode pattern.

Claims
