Abstract
A multi-layer ceramic electronic component, including: a capacitance forming unit that includes internal electrodes and ceramic layers, the internal electrodes being laminated in a first direction via the ceramic layers; and a circumferential unit that is provided on a circumference of the capacitance forming unit and formed of insulating ceramics. The circumferential unit includes a cover that is provided to the capacitance forming unit outward in the first direction, a side margin that is provided to the capacitance forming unit outward in a second direction orthogonal to the first direction, and a grain growth region that is formed at a boundary between the cover and the side margin and includes crystal grains of the insulating ceramics, the crystal grains having a mean grain size larger than a mean grain size of the crystal grains at a center portion of the cover.
