Abstract

Abstract A first terminal electrode has a first electrode portion disposed on a first face and connected to a first internal electrode, and a second electrode portion disposed on a third face and connected to the first electrode portion. A second terminal electrode has a first electrode portion disposed on a second face and connected to a second internal electrode, and a second electrode portion disposed on the third face and connected to the first electrode portion. Each of the second electrode portions of the first and second terminal electrodes, when viewed along a third direction perpendicular to the third face, is arranged with a gap in the second direction so as to sandwich at least a portion of an end in the first direction of an element body region sandwiched between the first internal electrode and the second internal electrode, at an end in the first direction of the second electrode portion.
