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 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 fiber sheet having first and second surfaces and spaces therein is prepared. The spaces of the fiber sheet are impregnated with silica sol containing water glass and ethylene carbonate. Silica gel is formed by causing the silica sol with which the spaces of the fiber sheet is impregnated to gel while a difference between respective temperatures at the first and surfaces of the fiber sheet is equal to or larger than 50° C. The silica gel is hydrophobized, thereby providing a thermal insulation sheet. In the thermal insulation sheet, compressibilities of the first and second surfaces for a predetermined pressure applied thereto are different from each other. The thermal insulation sheet may be disposed between two battery cells so as to prevent one sell from influencing the other even if the one expands.
