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.
