A multilayer ceramic electronic component includes a multilayer body that includes a second main surface defining and functioning as a mounting surface. Outer electrodes include underlying electrode layers including a conductive metal and a glass component and conductive resin layers including a thermosetting resin and a metal component. The underlying electrode layers extend from first and second end surfaces onto at least the second main surface. The conductive resin layers extend onto the underlying electrode layers provided on the second main surface, portions of the second main surface, and portions of the underlying electrode layers provided on the first end surface and the second end surface and cover portions of the first and second end surfaces, the portions including areas corresponding to about 9% or more and about 82% or less of areas of the first and the second end surfaces.

Multilayer ceramic electronic component

In a multilayer ceramic capacitor including outer electrodes electrically connected to inner electrodes of a ceramic body, a thickness of each of end portions of extension portions of the inner electrodes in a width direction is larger than a thickness of a corresponding one of middle regions in the width direction, and a distance from a first main surface of the ceramic body to a first auxiliary electrode closest to the first main surface is different from a distance from a second main surface of the ceramic body to a second auxiliary electrode closest to the second main surface in a stacking direction. Each of the first auxiliary electrode and the second auxiliary electrode has a continuity in the width direction of about 60% or more.

Multilayer ceramic capacitor

A multilayer ceramic capacitor includes a body and first and second outer electrodes. The body includes a multilayer unit with ceramic dielectric layers and conductive layers alternately stacked on each other. The body is sectioned into a thickness-direction inner layer section that includes the multilayer unit and thickness-direction first and second outer layer sections that sandwich the thickness-direction inner layer section therebetween. A dimension of the thickness-direction second outer layer section is greater than a dimension of the thickness-direction first outer layer section. A conductive layer closest to a first principal surface and a conductive layer closest to a second principal surface are first and second outermost conductive layers, respectively. A curving amount of an extension portion of the second outermost conductive layer is greater than that of an extension portion of the first outermost conductive layer.

A width of a second outermost conductive layer closest to a second principal surface of the body is smaller than a width of a central conductive layer closest to a center of the multilayer unit in the thickness direction. The thickness-direction second outer layer section includes an outer portion which defines the second principal surface and an inner portion disposed between the thickness-direction inner layer section and the outer portion, and a boundary portion disposed between the outer portion and the inner portion has a larger Si content than the outer portion.
