    • To obtain a protective device that can prevent overvoltage and at the same time has an excellent safety and also to make chip type protective devices smaller in size, this invention provides a protective device comprising a substrate, a heating element provided on the substrate, an insulating layer that covers the surface of the heating element, and a low-melting metal piece provided on the insulating layer. Particularly preferably the substrate and the heating element are each formed of an inorganic material. This protective device may be used in combination with a voltage detecting means making use of a zener diode, in such a way that the heating element of the protective device is electrically excited to generate heat when the voltage detecting means detects a voltage exceeding the rated voltage, whereby an overvoltage protector can be set up.
