A multilayer ceramic electronic component is provided in which wet spreading of a metal bump material can be suppressed and a position of the metal bump can be controlled with high accuracy. The multilayer ceramic electronic component includes a ceramic body having first and second main surfaces and first to fourth lateral surfaces between the main surfaces. Moreover, first and second opposing internal electrodes are provided inside the ceramic body and led out to one or more of the second lateral surfaces. A first electrode is provided on the first main surface and contains a ceramic material and a first external electrode that is connected to the first internal electrode, extends on the first electrode. In addition, a second external electrode is connected to the second internal electrode and extends onto the first main surface.

Multilayer ceramic electronic component and method for manufacturing same

The structure of a mother piezoelectric element allows a polarization process to be performed on the mother body before the individual piezoelectric elements are cut from the mother piezoelectric element. The mother piezoelectric element includes a plurality of first internal electrodes which are provided on at least one first surface and a plurality of second internal electrodes which are provided on at least one second surface. Each of the first and second internal electrodes is led out to any of first to fourth side surfaces of a mother piezoelectric body. The plurality of first internal electrodes are electrically connected to each other on a first surface and the plurality of second internal electrodes are electrical connected to each other on a second surface. All the first internal electrodes in the mother piezoelectric body are electrically connected to each other, and all the second internal electrodes in the mother piezoelectric body are electrically connected to each other.
