Provided is a PTC element formed by baking a base metal-based electrode onto a semiconductor ceramic composition, wherein the semiconductor ceramic composition has a perovskite structure consisting of a BaTiO3 type oxide, the base metal-based electrode contains, as a primary component, at least one of Al and Ni as a metal component and also contains at least B, and a low resistance layer, which has a lower resistance than the parent phase of the semiconductor ceramic composition, is formed on the base metal-based electrode side of the semiconductor ceramic composition. |
