Abstract: An element body includes first and second end surfaces opposing each other in a first direction, first and second side surfaces opposing each other in a second direction, and first and second principal surfaces opposing each other in a third direction. The length of the element body in the second direction is shorter than that of the element body in the first direction, and the length of the element body in the third direction is shorter than that of the element body in the second direction. A pair of first external electrodes is disposed at both ends of the element body in the first direction. A second external electrode is disposed on the element body and positioned between the pair of first external electrodes. The second external electrode includes a first conductor part disposed on the first side surface. A depression is formed in the first conductor part.

Abstract: In the sintered electrode layer covering the one end face, a wraparound dimension of a wraparound portion wrapping around from the one end face to the one main face in the facing direction is set to a dimension b, a distance between the one end face and the end portions of the plurality of second internal electrodes on the one end face side in the facing direction is set to a dimension Lg, a distance between the pair of main faces in the stacking direction is set to a dimension T, and a distance between the one main face and the second internal electrode closest to the one main face is set to a dimension Tg1, a relational expression of Lg>b−(2×b×Tg1/T) is satisfied.

Abstract: A first external electrode is disposed on an end surface. A second external electrode is disposed on a side surface. The first external electrode includes a first sintered electrode layer, a second sintered electrode layer disposed on the first sintered electrode layer, and a plated layer disposed on the second sintered electrode layer. The second external electrode includes a third sintered electrode layer and a plated layer disposed on the third sintered electrode layer. The first, second, and third sintered electrode layers include a void. A void fraction of each of the first and third sintered electrode layers is larger than a void fraction of the second sintered electrode layer.

Abstract: An element body includes first and second end surfaces opposing each other in a first direction, first and second side surfaces opposing each other in a second direction, and first and second principal surfaces opposing each other in a third direction. The length of the element body in the third direction is shorter than that of the element body in the first direction and is shorter than that of the element body in the second direction. A pair of first external electrodes is disposed at both ends of the element body in the first direction. Each of the first external electrodes includes a first conductor part disposed on one main surface and a second conductor part disposed on the end surface and coupled to the first conductor part. The porosity of the first conductor part is smaller than that of the second conductor part.
