Abstract
This surge absorber includes an insulating part upon which is formed a conductive layer which is divided into two separate portions by a discharge gap (micro gap) around its circumferential surface; a pair of terminal electrodes which are arranged to oppose the insulating part, and contacts the conductive layer; an insulating tube at the ends of which the terminal electrodes are arranged, and which seals the insulating part in its interior along with seal gases; and a conductive portion provided at least between the terminal electrodes and the conductive layer. As a result, it becomes possible to provide a surge absorber of lower cost, and which is endowed with stabilized performance and high quality, while moreover it exhibits excellent durability.
