| 简介 |
A laminated chip type varistor comprising a varistor function layer, internal electrodes, and terminal electrodes. The varistor function layer has a composition containing zinc oxide as a main component, and cobalt oxide and rare earth elements as additives. The internal electrodes contain at least one selected from the group consisting of aluminum in the form of Al2O3 with an amount of from 0.0001 to 5.0 % by weight, iron in the form of Fe2O3 with an amount of from 0.0001 to 5.0 % by weight, and zirconia in the form of ZrO2 with an amount of from 0.001 to 6.0 % by weight as additives with respect to an electrically conductive metal component of a composition for forming layers of the internal electrodes. |
