A varistor that faces another opposing electrode on the same plane with a certain distance between them, and that the varistor voltage generated between them is equal to the distance between the opposing electrodes on the same plane in the thickness direction of the fired body. A varistor characterized by being made larger than the voltage and smaller than the thickness of the fired body. (2) The varistor according to claim 1, wherein the counter electrode is an ohmic electrode. (3) The varistor according to claim 1, wherein the counter electrode is a non-ohmic electrode, and the varistor voltage generated in the thickness direction includes a contribution from a weir layer generated at the boundary between the electrode and the fired body. . (4) The varistor according to any one of claims 1, 2, and 3, wherein the fired body has a plate shape or a cylindrical shape whose main component is strontium titanate.
