Abstract

A ceramic capacitor and a method for manufacturing same, and comprises: a ceramic body including dielectric layers and having front and rear surfaces facing each other, upper and lower surfaces facing each other, and both end surfaces facing each other; a first edge cutting surface formed such that one end surface among both end surfaces of the ceramic body and the front and rear surfaces of the ceramic body meet each other; a second edge cutting surface formed such that the other end surface opposite to the one end surface among both end surfaces of the ceramic body and the front and rear surfaces of the ceramic body meet each other; at least one first internal electrode disposed and at least one second internal electrode.

Dependent claims

A ceramic capacitor comprising:

a ceramic body comprising a plurality of dielectric layers and comprising front and rear surfaces that face each other, upper and lower surfaces that face each other, and both end surfaces that face each other;
a first corner cutting plane formed to meet one end surface, among the both end surfaces of the ceramic body, and the front and rear surfaces of the ceramic body;
a second corner cutting plane formed to meet the other end surface that is opposite to the one end surface, among the both end surfaces of the ceramic body, and the front and rear surfaces of the ceramic body;
at least one first internal electrode disposed within the ceramic body and exposed to be connected to the one end surface of the ceramic body and the first corner cutting plane;
and
at least one second internal electrode disposed within the ceramic body, exposed to be connected to the other end surface of the ceramic body and the second corner cutting plane, and comprising a part that overlaps the first internal electrode.

A method of manufacturing a ceramic capacitor, comprising steps of:

manufacturing a ceramic sheet stack body by stacking a plurality of dielectric layers comprising a dielectric layer on which a first internal electrode has been printed and a dielectric layer on which a second internal electrode has been printed;
forming a through hole at each set location of the ceramic sheet stack body;
and
manufacturing a plurality of ceramic bodies in each of which first corner cutting planes are formed on both sides of one end surface thereof and second corner cutting planes are formed on both sides of the other end surface thereof by cutting the ceramic sheet stack body in a plurality of cell units so that the through hole is quartered on the basis of a center of the through hole.
