A multilayer ceramic capacitor that includes a ceramic body including a stack of a plurality of dielectric layers and a plurality of first and second internal electrodes; and first and second external electrodes provided at each of both end faces of the ceramic body. Each of the plurality of dielectric layers contain Ba, Ti, P and Si. The plurality of dielectric layers include an outer dielectric layer located on an outermost side in the stacking direction; an inner dielectric layer located between the first and second internal electrodes; and a side margin portion in a region where the first and second internal electrodes do not exist. In at least one of the outer dielectric layer, the inner dielectric layer and the side margin portion, the P and the Si segregate in at least one of grain-boundary triple points of three ceramic particles.

Multilayer ceramic capacitor

An electronic component includes a laminate in which a plurality of dielectric layers and a plurality of internal electrodes are alternately laminated and external electrodes electrically connected to the internal electrodes. A side margin portion as a region in which the plurality of internal electrodes is not provided when a section of the laminate having the length direction and the width direction is viewed from the laminating direction includes a plurality of side margin layers laminated in the width direction. An outer layer portion as a region in which the plurality of internal electrodes is not provided except for the side margin portion when a section of the laminate including the laminating direction and the width direction is viewed from the length direction includes a plurality of layer-margin layers laminated in the laminating direction.

Electronic component

A multilayer electronic component includes a multilayer body including dielectric layers and inner electrode layers. Each of the dielectric layers includes first crystal grains defining and functioning as plate-shaped objects that have an average thickness of less than or equal to about 300 nm and an average aspect ratio of more than or equal to about 5, each of the inner electrode layers includes second crystal grains defining and functioning as plate-shaped objects that have an average thickness of less than or equal to about 150 nm and an average aspect ratio of more than or equal to about 5, where an aspect ratio is represented by a ratio of a major axis of each plate-shaped object to a thickness of the plate-shaped object with the major axis of the plate-shaped object being orthogonal or substantially orthogonal to a thickness direction of the plate-shaped object.
