Abstract: A chip varistor includes an element body exhibiting varistor characteristics, internal electrodes containing a first electrically conductive material, and an intermediate conductor containing a second electrically conductive material. The intermediate conductor is separated from the internal electrodes in a direction in which the internal electrodes oppose each other, and is disposed between the internal electrodes. At least a part of the intermediate conductor overlaps the internal electrodes in the direction in which the internal electrodes oppose each other. The element body includes a low resistance region in which the second electrically conductive material is diffused. The low resistance region is located between the first and second internal electrodes in the direction in which the first and second internal electrodes oppose each other.

Abstract: A multilayer chip varistor includes an element body, first and second external electrodes, and first and second electrical conductor groups. The first electrical conductor group includes a first internal electrode connected to the first external electrode, and a first intermediate electrical conductor opposed to the first internal electrode. The second electrical conductor group includes a second internal electrode including a first electrically conductive material and connected to the second external electrode, and a second intermediate electrical conductor opposed to the second internal electrode. At least one of the first and second intermediate electrical conductors includes the second electrically conductive material. The element body includes a low electrical resistance region between the first and second internal electrodes. The second electrically conductive material is diffused in the low electrical resistance region.
