  • Patent number: 10553360
    Abstract: A body of a multilayer ceramic capacitor includes an inner layer portion and first and second outer layer portions sandwiching the inner layer portion therebetween. The inner layer portion includes an area extending from a conductive layer positioned closest to a first main surface to a conductive layer positioned closest to a second main surface in the stacking direction. The height of the body is smaller than the width of the body. The height of the inner layer portion is smaller than the width of the inner layer portion. The first outer layer portion includes a dielectric layer positioned closest to the first main surface. The second outer layer portion includes a dielectric layer positioned closest to the second main surface, and is thicker than the first outer layer portion. The total height of the first and second outer layer portions is smaller than the height of the inner layer portion.
