The present invention relates to a protector device, that is a device which protects other electronic devices from high voltage or large current, that is surge. The protector device (10) according to the present invention utilizes breakdown phenomena of resistive oxide films (12) on the metal bars (11). The metal bars (11) are surrounded by a mixture (14) of oxidizing agent and refractory agent. The protector device returns from conductive state to non-conductive state in a very short time because the surface of the metal bar is oxidized automatically due to the constitution described above. |
