Abstract
A method of manufacturing a chip capacitor according to an aspect may include: preparing a capacitor lamination including a dielectric sheet formed of a composite having ceramic powder and a polymer mixed with each other, and first and second internal electrodes formed on both surfaces of the dielectric sheet at predetermined intervals; forming covering layers formed of an insulating material on both surfaces of the capacitor lamination; forming a first opening and a second opening in the capacitor lamination having the covering layers formed thereon to expose the first and second internal electrodes, respectively; forming plating layers in the first and second openings, the plating layers connected to the first and second internal electrodes; and dicing the capacitor lamination into chips on the basis of the first and second openings so that the plating layers formed in the first and second openings are provided as first and second external terminals.
