Abstract:
1. A multilayer chip varistor comprising: a multilayer body in which a plurality of varistor portions are arranged along a predetermined direction, each of said varistor portions having a varistor layer to exhibit nonlinear voltage-current characteristics and a plurality of internal electrodes disposed so as to interpose the varistor layer between the internal electrodes; and a plurality of terminal electrodes disposed on a first outer surface of the multilayer body, wherein the first outer surface extends in a direction parallel to the predetermined direction; a plurality of pad electrodes disposed on a first outer surface of the multilayer body, facing the first outer surface, and a resistor disposed on the second outer surface wherein each of the plurality of internal electrodes comprises: a first electrode portion overlapping with another first electrode portion between adjacent internal electrodes in a laminate direction of the multilayer body out of the plurality of internal electrodes; and a second electrode portion led from the first electrode portion so as to be exposed in the first outer surface, wherein one terminal electrode out of the plurality of terminal electrodes is electrically connected via the second electrode portion to one internal electrode out of said adjacent internal electrodes in the laminate direction, and another terminal electrode out of the plurality of terminal electrodes is electrically connected via the second electrode portion to another internal electrode out of said adjacent internal electrodes in the laminate direction, the second electrode portion of one internal electrode out of said adjacent internal electrodes is led so as to be exposed in the second outer surface and each of the plurality of pad electrodes is electrically connected via the second electrode portion to said one internal electrode corresponding thereto, and the resistor disposed on the second outer surface is electrically connected to a pair of pad electrodes out of the plurality of pad electrodes.
