Abstract

A surge-absorbing element with a function of protection from overvoltage and overcurrent in which a metal wire mechanically and elastically deformed and having high rigidity is joined with a low-melting metal to a terminal or to a lead wire of a gap-type or microgap-type surge-absorbing element. In case the surge-absorbing element generates heat due to overvoltage and overcurrent, the low-melting metal melts, the elastically deformed rigid metal wire separates from the terminal or lead wire, and the connection is broken. The rigid metal wire is connected in series with the surge-absorbing element and a device or a circuit that is to be protected.
