Abstract

See full text

A surge absorbing element includes a varistor substrate, a pair of electrodes that are electrically connected to both end faces of the varistor substrate, respectively, to sandwich the varistor substrate, external leads that electrically connect to the paired electrodes, respectively, exterior members that cover the electrodes, and a thermal expansion body that is provided between the paired electrodes and that irreversibly expands with heat generated by the varistor substrate to separate at least one of the paired electrodes from the varistor substrate. A temperature at which the thermal expansion body starts expanding is, for example, equal to or higher than 180° C.
