Abstract
A multilayer capacitor includes: a capacitor body including dielectric layers and first and second internal electrodes, and having first to six surfaces; first and second side portions disposed on the fifth and sixth surfaces of the capacitor body, respectively, and having roughnesses on surfaces thereof; a first external electrode disposed on the third surface of the capacitor body and parts of the first and second side portions and connected to the first internal electrodes; and a second external electrode disposed on the fourth surface of the capacitor body and parts of the first and second side portions and connected to the second internal electrodes.

A multilayer capacitor comprising:
- a capacitor body including dielectric layers and first and second internal electrodes, and having first and second surfaces opposing each other, third and fourth surfaces connected to the first and second surfaces and opposing each other, and fifth and sixth surfaces connected to the first and second surfaces, connected to the third and fourth surfaces, and opposing each other;
- first and second side portions disposed on the fifth and sixth surfaces of the capacitor body, respectively, and having a roughness on surfaces thereof;
- a first external electrode disposed on the third surface of the capacitor body, covering first parts of the first and second side portions, and connected to the first internal electrodes;
- and
- a second external electrode disposed on the fourth surface of the capacitor body, covering second parts of the first and second side portions, and connected to the second internal electrodes,
- wherein the first parts of the first and second side portions covered by the first external electrode and the second parts of the first and second side portions covered by the second external electrode have the roughness, and
- the roughness of the first and second side portions is greater than a roughness of one of the third and fourth surfaces.
A multilayer capacitor comprising:
- a body including a ceramic body, in which dielectric layers and first and second internal electrodes are stacked, the body having first and second surfaces opposing each other in a stacking direction of the first and second internal electrodes, third and fourth surfaces from which the first and second internal electrode are respectively exposed, and fifth and sixth surfaces opposing each other;
- a first external electrode disposed on the third surface of the body and parts of the fifth and sixth surfaces, and connected to the first internal electrodes;
- and
- a second external electrode disposed on the fourth surface of the body and parts of the fifth and sixth surfaces, and connected to the second internal electrodes,
- wherein a roughness of one of the fifth and sixth surfaces is greater than a roughness of one of the first and second surfaces.
