Abstract
A multilayer capacitor includes an element body, and a pair of side surfaces and a pair of main surfaces; and a pair of external electrodes. The element body includes an inner layer portion in which a plurality of internal electrodes and a plurality of dielectric layers are alternately stacked in a second direction where the pair of main surfaces face each other, and a pair of outer layer portions disposed outside the inner layer portion in the second direction. On at least one of the pair of end surfaces, the internal electrode of the inner layer portion protrudes outward in the first direction from the outer layer portion by a predetermined protrusion amount. A ratio of the protrusion amount to a dimension of the element body in the second direction ranges from 11,000 ppm to 16,000 ppm.
