Abstract: An electronic component includes external nickel layers each provided on end surfaces of a multilayer body and external copper electrode layers each covering the end surfaces on which the external nickel layers are provided. When a dimension of each of the external nickel layers in the lamination direction is defined as TN, and a dimension of the inner layer portion in the lamination direction is defined as T1, T1

Abstract: A multilayer ceramic capacitor includes a multilayer main body including an inner layer portion including dielectric layers and internal electrode layers alternately stacked, and outer layer portions on both sides of the inner layer portion in a stacking direction, two external electrodes at two end surfaces of the multilayer body in which side gap portions are provided on both sides of the multilayer main body in the width direction, and an interposer on any of the main surfaces, the side surfaces, and the end surfaces of a capacitor main body including the multilayer and the external electrodes. The difference in location between ends at side surfaces of two adjacent internal electrode layers in the stacking direction is about 0.5 μm or less. In the two side gap portions, a portion in contact with the multilayer main body has a thickness of about 10 μm or less.

Abstract: A multilayer ceramic capacitor includes a multilayer body and external electrodes. The multilayer body includes an inner layer portion including dielectric layers and internal electrode layers alternately stacked, and first and second outer layer portions on opposite sides of the inner layer portion in a stacking direction, side gap portions on opposite sides in a width direction, main surfaces on opposite sides in the stacking direction, side surfaces on opposite sides in the width direction, and end surfaces on opposite sides in a length direction. Each external electrode is provided at one end surfaces of the multilayer body, and extends from the end surface to a portion of the main surface. A difference in location between ends at the side surface of two adjacent internal electrode layers is about 0.5 μm or less. The second outer layer portion is thicker than the first outer layer portion.

Abstract: A three terminal capacitor includes a capacitor element including first through sixth surfaces, first-side and second-side outer electrodes, a center outer electrode between the first-side and second-side outer electrodes, and conductor layers. The conductor layers include a pair of outermost conductor layers that are respectively nearest to the fifth and sixth surfaces, and thicknesses of the pair of outermost conductor layers are greater than a thickness of a center conductor layer nearest to a center of the capacitor element in a width direction.
