<p>An electronic part with safe-guard function having an element which protects the circuit from abnormally high voltages and cuts off the excess current when an overvoltage continues. The electronic part is used for preventing a surge-absorbing element (21) and the circuitry from burning. The electronic part with safe-guard function comprises the surge-absorbing element (21), a low-melting-point metal element (23) which is electrically connected in series with the surge-absorbing element (21) and is in contact with the same so that the heat conduction between them is good, and a heat-shrinkable insulating tube (25) that covers the peripheral surfaces of the surge-absorbing element (21) and the low-melting-point metal element (23).</p> |
