る等の欠点を有している。 Generally, in a discharge tube type surge absorbing element, when a surge voltage is applied to the electrodes and discharge starts, the electrodes are electrically shorted and the surge is absorbed. When a voltage equal to or higher than the arc sustaining voltage is applied between the electrodes of this surge absorbing element, a follow-on current occurs. In order to block this follow-on current, the conventional discharge tube type surge absorbing device has a configuration in which a resistor, for example, a wire-wound resistor 8, is connected in series to the discharge tube type surge absorbing element 7, as shown in FIG. It's on. Although the circuit with this configuration has excellent follow-current blocking properties, it has disadvantages such as the need to attach the surge absorbing element and the resistor separately on the board, which is time-consuming and occupies a large area on the board. ing.
