Abstract: A multilayer varistor has a stack structure including a plurality of layers stacked in a third direction. The multilayer varistor includes a first internal electrode electrically connected to a first external electrode, a second internal electrode electrically connected to the second external electrode, and a third internal electrode electrically connected to the third external electrode. The first internal electrode is disposed between the second internal electrode and the third internal electrode in the third direction.

Abstract: A stacked varistor having a small variation in electrostatic capacitance is obtained. The stacked varistor includes first internal electrode projection extending from third internal electrode toward first end surface between first side surface and first varistor region, and second internal electrode projection extending from third internal electrode toward second end surface between first side surface and second varistor region. First internal electrode projection extends closer to first end surface than a line connecting point closest to first end surface of first varistor region and point closest to first end surface of third external electrode is. Second internal electrode projection extends closer to second end surface than a line connecting point closest to second end surface of second varistor region and point closest to second end surface of third external electrode is.
