A multilayer varistor includes a sintered body, an internal electrode disposed in the sintered body, a high-resistance layer covering at least part of the sintered body, and an external electrode covering part of the high-resistance layer, the external electrode being electrically connected to the internal electrode. An arithmetic mean roughness of a surface of the high-resistance layer is greater than or equal to 0.06 μm.
