Claim Text:
1. 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, overlapped with each other, and spaced away from edges of the dielectric layers, and first and second lead out portions having a mutual overlap region and extending from one surface 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 the one surface of the ceramic body and electrically connected to the first and second lead out portions, respectively; and an insulating layer formed on the one surface of the ceramic body and covering exposed portions of the first and second lead out portions, wherein inner connection portions, formed between the first body portion and the first lead out portion and between the second body portion and the second lead out portion, have a concave curved surface formed in a region overlapping the second lead out portion and the first lead out portion, respectively, wherein when it is defined that a point starting from the first or second lead out portion of the inner connection portion is x′, a point starting from the first or second body portion is y′, a point at which a line extending from x′ along a front edge surface of the first or second lead out portion in a width direction and a line extending from y′ along a front edge surface of the first or second body portion in a length direction meet is o, a point at which a line extending along one exposed lateral surface of the first or second lead out portion and a line extending along one end surface of the first or second body portion meet is c, a point at which a straight line extending to connect o and c and the inner connection portion meet is a, and a point at which a straight line connecting x′ and y′ and the straight line extending to connect o and c meet is a′, a length of a segment oa is less than or equal to a length of a segment oa' and the length of the segment oa is less than or equal to 0.5×a length of a segment oc, and wherein the first and second internal electrodes further respectively include third and fourth lead out portions that are partially overlapped with each other and respectively extend from another surface of a respective one of the first and second body portions so as to be exposed to another surface of the ceramic body opposing the one surface thereof, wherein each of inner connection portions formed between the first and second body portions and the third and fourth lead out portions has a concave curved surface, wherein corners of the first and second body portions of the first and second internal electrodes are of a different type than corners between the first and second lead out portions and the first and second body portions, such that corners of the first and second body portions of the first and second internal electrodes are substantially right-angled corners and corners between the first and second lead out portions and the first and second body portions are curved, and wherein the inner connection portions between the first and second body portions and the first and second lead out portions are of different shapes on different sides of the first and second lead out portions, such that one side of the first lead out portion is aligned with one side of the first body portion and is connected thereto by a straight surface while another side of the first lead out portion is connected to the first body portion by the concave curved surface, and one side of the second lead out portion is aligned with one side of the second body portion and is connected thereto by a straight surface while another side of the second lead out portion is connected to the second body portion by the concave curved surface.
