Abstract
There is provided a multilayer ceramic capacitor including: a ceramic body; a plurality of first and second internal electrodes including first and second body portions and first and second lead out portions, respectively; first and second external electrodes formed on one surface of the ceramic body, respectively; and an insulating layer formed on one surface of the ceramic body and covering exposed portions of the first and second lead out portions, wherein inner connection portions between the first and second body portion and the first and second lead out portions may have a concave curved surface, respectively.
Claims18
A multilayer ceramic capacitor comprising:
- a ceramic body in which a plurality of dielectric layers are laminated;
- a plurality of first and second internal electrodes including first and second body portions alternately formed on the plurality of dielectric layers and overlapped with each other and first and second lead out portions having a mutual overlap region and extending from one surfaces of the first and second body portions so as to be exposed to one surface of the ceramic body, respectively;
- first and second external electrodes formed on one surface of the ceramic body and electrically connected to the first and second lead out portions, respectively;
- and
- an insulating layer formed on one surface of the ceramic body and covering exposed portions of the first and second lead out portions,
- wherein inner connection portions between the first and second body portion and the first and second lead out portions have a concave curved surface, respectively.
A method of manufacturing a multilayer ceramic capacitor, the method comprising:
- forming a first internal electrode on a first ceramic sheet, the first internal electrode including a first body portion and a first lead out portion extending from one surface of the first body portion so as to be exposed to one surface of the first ceramic sheet, and an inner connection portion of the first body portion and the first lead out portion of the first internal electrode having a concave curved surface;
- forming a second internal electrode on a second ceramic sheet, the second internal electrode including a second body portion and a second lead out portion extending from one surface of the second body portion so as to be exposed to one surface of the second ceramic sheet, and an inner connection portion of the second body portion and the second lead out portion of the second internal electrode having a concave curved surface;
- alternately laminating a plurality of first and second ceramic sheets with the first and second internal electrode formed thereon, and firing the same to form a ceramic body;
- forming first and second external electrodes on one surface of the ceramic body such that the first and second external electrodes are electrically connected to the first and second lead out portions;
- and
- forming a first insulating layer on one surface of the ceramic body to cover exposed portions of the first and second lead out portions.
