Abstract:
1. A multilayer ceramic electronic component comprising: a ceramic body including a pair of opposing principal surfaces, a pair of opposing side surfaces, a pair of first and second opposing end surfaces, and a plurality of ceramic layers that extend in a direction in which the principal surfaces extend and are stacked in a direction of a line that connects the pair of principal surfaces, a dimension of the end surfaces in a direction of a line that connects the pair of side surfaces is smaller than a dimension of the side surfaces in a direction of a line that connects the pair of end surfaces; a first internal electrode that is arranged inside the ceramic body and that includes a first led out portion that provides an exposed end that is exposed at the first end surface, and a first opposing portion; a second internal electrode that is arranged inside the ceramic body and that includes a second led out portion that provides an exposed end that is exposed at the second end surface opposed to the first end surface, and a second opposing portion opposed to the first opposing portion; an external electrode that is arranged on one of the first and second end surfaces so as to be electrically connected to one of the first and second internal electrodes; wherein the external electrode includes a first conductive portion that is arranged on the one of the first and second end surfaces so as to cover the exposed end of one of the first and second led out portions and so as not to wrap around onto the side surfaces, and includes a second conductive portion that is arranged on the one of the first and second end surfaces so as to cover the first conductive portion and so as to wrap around onto the principal surfaces and the side surfaces; the external electrode does not include any insulating layers, nor are any insulating layers arranged between the first and second internal electrodes and the external electrode; a width of the first led out portion is less than a width of the first opposing portion and a width of the second led out portion is less than a width of the second opposing portion; the external electrode further includes a third conductive portion that wraps around and encapsulates all exposed portions of the second conductive layer; the external electrode includes a protruding portion that is arranged on the one of the first and second end surfaces so as to be adjacent to the first conductive portion with a predetermined distance therebetween; the protruding portion is electrically connected to the one of the first and second internal electrodes only through the first, second, and third conductive portions; and the protruding portion is spaced away from the first led out portion or the second led out portion exposed at the one of the first and second end surfaces.
