Title:
サージ防護素子及びその製造方法
Document Type and Number:
Japanese Patent JP6801407
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a surge protective element which can suppress expansion of an ion source material, and can achieve high adhesion and crystallinity; and a manufacturing method of the surge protective element.SOLUTION: A surge protective element comprises: an insulation tube 2; and a pair of sealing electrodes 3 which close openings on both ends of the insulation tube so as to internally seal discharge control gas. The pair of sealing electrodes have a pair of protruding electrode parts 5 which protrude inward so as to face each other. Facing faces 5a of the pair of protruding electrode parts are each provided with a porous metal layer 8. At the same time, a discharge active layer 9, which is made of a material having a superior electron emission characteristic to that of the sealing electrodes, is formed on the surface of the porous metal layer in such a manner that at least part thereof is embedded in the porous metal layer.SELECTED DRAWING: Figure 1
