Abstract
An aggregate substrate has a first varistor part, a second varistor part, and a heat dissipation layer. The first varistor part includes a first varistor element layer to exhibit nonlinear voltage-current characteristics, and a plurality of first internal electrodes juxtaposed in the first varistor element layer. The second varistor part includes a second varistor element layer to exhibit nonlinear voltage-current characteristics, and a plurality of second internal electrodes juxtaposed in the second varistor element layer. The heat dissipation layer is located between the first and second varistor parts and is in contact with the first and second varistor parts.
