Abstract
A multi-layer ceramic capacitor having a weight of 8 mg or more includes a capacitance forming unit and a protective unit. The capacitance forming unit includes internal electrodes that are laminated in a first direction and includes end portions, positions of the end portions in a second direction orthogonal to the first direction being aligned with one another within a range of 0.5 μm in the second direction. The protective unit covers the capacitance forming unit in the first direction and the second direction and includes an outer surface, a shortest distance between the outer surface and the end portion of an outermost layer in the internal electrodes in the first direction exceeding 10 μm.
