Patent ID: 8717738

Claim:
A multilayer ceramic electronic component comprising: an element body including a pair of principal surfaces facing each other, a pair of side surfaces facing each other, and a pair of end surfaces facing each other, rounded chamfer portions located along ridgelines between the side surfaces and the end surfaces, and a plurality of ceramic layers extending in a principal surface direction and laminated in a direction perpendicular or substantially perpendicular thereto and a plurality of pairs of internal electrodes which are provided along interfaces between the ceramic layers, which each include an exposure end exposed to one of the pair of end surfaces, and which are not exposed to the side surfaces; external electrodes provided at least on the pair of end surfaces of the element body so as to be electrically connected to the exposure ends of the internal electrodes; and dummy electrodes provided along the interfaces between the ceramic layers; wherein each of the internal electrodes includes: a facing portion including two sides parallel or substantially parallel to the side surfaces of the element body and facing an adjacent internal electrode with at least one of the ceramic layers interposed therebetween; and an extending portion extending from the facing portion to one of the end surfaces of the element body to define the exposure end at the end of the extending portion; wherein a width of the exposure end of the extending portion is smaller than a width of the facing portion when viewed in a width direction between the side surfaces of the element body so as to define margin regions at two sides of the extending portion and between the two sides of the extending portion and the respective side surfaces of the element body; the dummy electrodes are provided in the margin regions of each of the internal electrodes; and in regions of the margin regions of each of the internal electrodes between extension lines of the two sides of the facing portion that are parallel or substantially parallel to the side surfaces of the element body and the respective two sides of the extending portion, the dummy electrodes are arranged so as not to extend to the extension lines of the two sides of the facing portion that are parallel or substantially parallel to the side surfaces of the element body.
