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.

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 multilayer ceramic component according to the present disclosure includes a sintered body, a plurality of internal electrodes, and a side surface electrode. The side surface electrode includes: a primary electrode layer containing silver as a main component thereof; and a plating layer covering the primary electrode layer at least partially. The primary electrode layer includes a first terminal portion provided for the side surface of the sintered body and a second terminal portion. The second terminal portion extends, in a second direction, from at least one of a pair of end portions of the first terminal portion in a third direction and is provided for at least one of a pair of principal surfaces. An interposed portion is formed by allowing a part of the plating layer to enter a region where a tip of the second terminal portion and the sintered body are separate from each other.
