Abstract

An element body includes a first function portion including a first material, a second function portion including a second material different from the first material, and an intermediate portion placed between the first function portion and the second function portion. The intermediate portion includes a first component included in the first material, and a second component included in the second material. A side surface of the element body includes surfaces of the first function portion, the second function portion, and the intermediate portion. Each of terminal electrodes includes electrode portion formed on the side surface across the surfaces of the first function portion, the second function portion, and the intermediate portion. An insulating layer is formed on the side surface in such a manner as to be in contact with at least a region exposed from the electrode portions between the electrode portions in the surface of the intermediate portion.
