Abstract: An element body of a rectangular parallelepiped shape includes a first principal surface arranged to constitute a mounting surface, a second principal surface opposing the first principal surface in a first direction, a pair of side surfaces opposing each other in a second direction, and a pair of end surfaces opposing each other in a third direction. An external electrode is disposed on the element body. The external electrode includes a conductive resin layer. The conductive resin layer continuously covers one part of the first principal surface, one part of the end surface, and one part of each of the pair of side surfaces. A length of the conductive resin layer in the first direction is smaller than a length of the conductive resin layer in the third direction.

Abstract: A length in a third direction of a first connection portion is smaller than a length in the third direction of a first main electrode portion. A length in the third direction of a second connection portion is smaller than a length in the third direction of a second main electrode portion. A thickness in a first direction of an inner layer portion is smaller than each of the length in the third direction of the first connection portion and the length in the third direction of the second connection portion and smaller than each of a gap from a second side surface to the first connection portion in the third direction and a gap from the second side surface to the second connection portion in the third direction. The second side surfaces oppose each other in the third direction perpendicular to the first direction.

Abstract: An element body includes a main surface and a pair of end surfaces. Each external electrode includes a conductive resin layer on the main surface. Each auxiliary internal electrode is disposed in the same layer as a corresponding internal electrode of a plurality of internal electrodes and is electrically connected to the external electrode to which the corresponding internal electrode is not electrically connected. Each auxiliary internal electrode includes first and second electrode portions. The first electrode portion is exposed to a corresponding end surface of the pair of end surfaces and is electrically and physically connected to the external electrode to which the corresponding internal electrode is not electrically connected. The second electrode portion is positioned between the conductive resin layer of the external electrode to which the corresponding internal electrode is not electrically connected and the corresponding internal electrode.

Abstract: An element body of a rectangular parallelepiped shape includes a principal surface arranged to constitute a mounting surface, a pair of side surfaces opposing each other and adjacent to the principal surface, and a pair of end surfaces opposing each other and adjacent to the principal surface and the pair of side surfaces. An external electrode includes a sintered metal layer disposed on an end portion of the element body, and a conductive resin layer including a portion positioned on the principal surface and a portion positioned on the sintered metal layer. An end edge of the sintered metal layer is positioned closer to the end surface than a maximum thickness position of the portion positioned on the principal surface. A thickness of the conductive resin layer gradually decreases from the maximum thickness position to the portion positioned on the sintered metal layer.
