た。 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. Conventional discharge tube type surge absorbing elements attach a conductive thin film to the surface of an insulator, divide the conductive thin film into multiple pieces via filaments, and fix electrodes to each of the divided ends of the conductive thin film. A single surge absorber is made by electrically connecting electric wires to the electrodes, and is surrounded by an insulating coating, and a gas is sealed in the surge absorber. The operation of adding streaks, or adding gas to a predetermined composition,
It has the disadvantage that its characteristics tend to vary due to variations in pressure-enclosing operations and the like. Therefore, a plurality of such discharge tube type surge absorption elements are electrically connected as shown in Fig. 1 (two in the figure) to reduce the surge voltage between A and A' and between A and A''. is applied, a difference arises in the responsiveness of discharge between the surge absorbing elements 8a and 8a, resulting in the disadvantage that the surges cannot be absorbed simultaneously.
