Abstract: A first internal electrode includes a pair of first connecting parts extending from a first end surface along a first direction to be connected to a first external electrode, and a first facing part provided between the pair of first connecting parts. A second internal electrode includes a pair of second connecting parts extending from a second end surface along the first direction to be connected to a second external electrode, and a second facing part provided between the pair of second connecting parts. A third internal electrode includes a third facing part disposed along the first direction. The third facing part overlaps the first facing part and the second facing part. A first end of the third facing part is disposed between the pair of first connecting parts, and a second end of the third facing part is disposed between the pair of second connecting parts.

Abstract: A laminated varistor includes a sintered body and first to third internal electrodes provided inside the sintered body. The first internal electrode includes a first facing part facing the third internal electrode in a third direction, and a first connecting part connecting the first facing part and the first external electrode. The second internal electrode includes a second facing part facing the third internal electrode in the third direction, and a second connecting part connecting the second facing part and the second external electrode. The first connecting part includes a first connection portion connected to the first external electrode, and a first narrow part having a dimension in a second direction smaller than the first connection portion. The second connecting part includes a second connection portion connected to the second external electrode, and a second narrow part having a dimension in the second direction smaller than the second connection portion.

Abstract: It is aimed to provide a laminated varistor capable of reducing stray capacitance to occur between an internal electrode and an external electrode, and also capable of reducing a variation in the stray capacitance due to a variation in the external electrode. A laminated varistor of the present disclosure has external electrodes on first end surface, second end surface, and first side surface of sintered body. No external electrode is provided on second side surface opposite to first side surface. Varistor regions in which internal electrodes overlap each other in a laminating direction are provided at positions closer to second side surface than to first side surface.
