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.
