摘要： An multilayer ceramic capacitor includes external electrodes including metal layers on first and second end surfaces so as to cover internal electrodes extending to the first and second end surfaces, respectively, glass films on the first and second end surfaces, adjacent to the metal layers and extending around the metal layers, fired layers including glass and metal, and covering the metal layers, and plating films covering the fired layers. The fired layers include voids including plating material in at least a portion thereof.

摘要： When a multilayer ceramic capacitor is viewed as a section of a central portion in a width direction cut parallel or substantially parallel or substantially parallel or substantially parallel to a side surface, in an internal electrode layer in a central portion in a lamination direction and including an extremity spaced apart from an end surface, any one of five segments of the internal electrode layer that are horizontally and successively positioned from the extremity has a length greater than about 0.2 times of an average length of ten segments of the internal electrode layer that are horizontally and successively positioned in a central portion in a length direction.

摘要： In a multilayer ceramic capacitor, a dimension of each of first and second extension portions in a width direction is less than a dimension of a first counter electrode portion in the width direction, and a dimension from a side of each of the first and second extension portions near a first lateral surface to the first lateral surface in the width direction and a dimension from a side of each of the first and second extension portions near a second lateral surface to the second lateral surface in the width direction are each greater than the dimension of each of the first and second extension portions in the width direction.

摘要： A three-terminal multilayer ceramic capacitor includes at least one surface electrode layer on a surface of a second internal electrode layer connected to a lateral surface external electrode. The surface electrode layer includes at least one of Sn, In, Ga, Zn, Bi, Pb, Fe, V, Y or Cu, which is different from a main component of the second internal electrode layer.

摘要： A ceramic electronic component includes a ceramic main body in which dielectric layers and internal electrodes are laminated, the ceramic main body including a pair of principal surfaces, a pair of side surfaces, and a pair of end surfaces, the internal electrodes are exposed to the end surfaces, and an underlayer external electrode covers at least a portion of the end surface. When a section of the ceramic main body is viewed, the underlayer external electrode is discontinuously provided on the ceramic main body. The ceramic main body includes an exposed region partially exposed from the discontinuously provided underlayer external electrode, the exposed region is covered with a resin layer, and the underlayer external electrode is covered with a plating film.
