する避雷器。 A plurality of wart-shaped protrusions are provided on the pressure contact surface of the electrode plate that is in pressure contact with one or both of the metallicon electrode surfaces of the varistor element, and the tips of the protrusions are in contact with the metallicon electrode of the varistor element to ensure electrical conductivity. A lightning arrester characterized in that current density to the varistor element is controlled by the density of the convex portions on the electrode plate.
