Abstract: A multilayer ceramic capacitor includes a laminated body and first and second external electrodes respectively on both end surfaces of the laminated body. When regions where first internal electrodes or second internal electrodes are not present are regarded as side margin portions in a cross section of the laminated body as viewed from the laminating direction, the side margin portions include multiple side margin layers, and the content of Si in the side margin layer closest to the internal electrode is lower than that in the side margin layer other than the side margin layer closest to the internal electrode.

Abstract: 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.
