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: A laminated ceramic component includes a sintered body, internal electrodes provided inside the sintered body, and external electrodes provided on a surface of the sintered body and electrically connected to the internal electrodes. The external electrodes include a first end-surface electrode provided on at least a portion of a first end surface of the sintered body, a second end-surface electrode provided on at least a portion of a second end surface of the sintered body, a first side-surface electrode provided on a portion of a first side surface of the sintered body, and a second side-surface electrode provided on a portion of a second side surface of the sintered body. Each of the first and second end-surface electrodes and the first and second side-surface electrodes contains metal and glass component. A content of the glass component in each of the first and second end-surface electrodes is different from a content of the glass component in each of the first and second side-surface electrodes.

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.
