Abstract: An electronic component includes: a first internal electrode provided in an element body; a second internal electrode provided in the element body; a third internal electrode provided in the element body and drawn out to a first side surface; and a fourth internal electrode provided in the element body and drawn out to a second side surface. The third internal electrode and the fourth internal electrode are electrically connected to each other through an external connection conductor formed on at least the first side surface and the second side surface. In a first direction, the first internal electrode faces the third internal electrode without facing the second internal electrode and the fourth internal electrode. In the first direction, the second internal electrode faces the fourth internal electrode without facing the first internal electrode and the third internal electrode.

Abstract: A multilayer ceramic electronic device includes an element body including a ceramic layer and an internal electrode layer, and an external electrode formed on an outer surface of the element body and electrically connected to part of the internal electrode layer. The external electrode includes a first layer in direct contact with the element body and containing a first insulator phase and first metal phases, and a second layer in contact with an outer surface of the first layer and containing a second insulator phase and second metal phases. An area ratio of the first metal phases in the first layer is more than 8% and 30% or less. An area ratio of the second metal phases in the second layer is larger than the area ratio of the first metal phases in the first layer. The first metal phases have an average aspect ratio of 3.5 or more.
