Abstract
A chip type varistor in which first and second inner electrodes are embedded in a sintered body obtained by laminating a plurality of semiconductor ceramics layers so as not to be overlapped with each other in the direction of thickness of the ceramics layers, respective one edges of the first and second inner electrodes are led out to one and the other of a pair of side surfaces opposed to each other of the sintered body and are electrically connected to outer electrodes formed on the pair of side surfaces of the sintered body, respectively, a non-connected type inner electrode which is not electrically connected to the above described outer electrodes is embedded in the sintered body, and the non-connected type inner electrode is arranged so as to be overlapped with the first and second inner electrodes while being separated by the semiconductor ceramics layer.
