Multilayer ceramic capacitor and method of manufacturing the same

A multilayer ceramic capacitor comprising:

• a ceramic body including an active portion including dielectric layers and a plurality of internal electrodes overlapping each other across the dielectric layers, and upper and lower cover portions formed above and below the active portion, respectively, and including first and second surfaces opposing each other, third and fourth surfaces connecting the first and second surfaces, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other;
• and
• first and second side margin portions disposed on the first and second surfaces,
• wherein the plurality of internal electrodes include body portions, and lead portions that have a smaller width than the body portions and have an end portion in contact with the third or fourth surface;
• wherein surfaces of the body portions are in contact with the first and second surfaces of the ceramic body and the first and second side margin portions are disposed on the surfaces of the body portions,
• wherein, in a cross-section of the ceramic body in a length-thickness (L-T) direction, a ratio Sd/Sc of an area Sd of a region except for the active portion to an overall area Sc of the cross-section is greater than 27%,
• wherein the cross-section of the ceramic body in the length-thickness (L-T) direction is a cross-section in a region between width-direction opposite ends of the body portions of the plurality of internal electrodes and between a portion of width-direction opposite ends of the lead portions,
• wherein a ratio of a thickness of a region of the first or second side margin portion, contacting edges of the plurality of internal electrodes disposed as an outermost portion, to a thickness of a region of the first or second side margin portion, contacting edges of the plurality of internal electrodes disposed in a central portion among the plurality of internal electrodes, is within a range from 0.9 and 1.0,
• wherein a ratio of a thickness of a region of the first or second side margin portion, contacting an edge of the ceramic body, to the thickness of the region of the first or second side margin portion, contacting the edges of the plurality of internal electrodes disposed in the central portion among the plurality of internal electrodes, is within a range from 0.9 and 1.0,
• wherein each of the upper and lower cover portions has a thickness equal to or less than 20 μm, and
• an average thickness of the first side margin portion and the second side margin portion is between 2 μm and 10 μm.
