Abstract:
A laminated-type varistor comprising:a laminated structure in which a plurality of effective sintered body layers each exhibiting varistor characteristics and a plurality of internal electrodes each having thermal conductivity higher than that of said effective sintered body layers are layered in a direction of lamination; anda pair of external electrodes disposed on a surface of said laminated structure, whereinof said plurality of internal electrodes, a plurality of adjacent pairs of said internal electrodes, each said pair being connected to a corresponding one of said external electrodes and said electrodes of each said pair being spaced apart from each other in said lamination direction, so as to define a multilayer electrode structure, wherein an ineffective sintered body layer not contributing to varistor characteristics is disposed between each said adjacent pair of internal electrodes.
