ABSTRACT:
A first varistor section includes a first face of an element body, and a third face facing the first face. The first varistor section has a first varistor element body, a first varistor electrode electrically connected to a first external electrode, and a second varistor electrode electrically connected to a second external electrode. A heat radiation section has a first heat radiation portion kept in contact with the third face of the first varistor section and electrically connected to the first and third external electrodes, a second heat radiation portion kept in contact with the third face of the first varistor section and electrically connected to the second and fourth external electrodes, and an insulating layer located between the first heat radiation portion and the second heat radiation portion and electrically insulating the first heat radiation portion and the second heat radiation portion from each other. The first heat radiation portion and the second heat radiation portion contain a metal.
