Title:
放電素子およびその製造方法
Document Type and Number:
Japanese Patent JP5010052
Kind Code:
B1
Abstract:
A discharge element includes a first electrode that is made of a plastically-deformable conductive material and that has an internal space and an opening communicating with the internal space, a base that is made of an insulating material and that is air-tightly joined to the opening so that the internal space of the first electrode becomes an airtight space, and a second electrode that is made of a conductive material and that is inserted into the internal space via the base so as to form a spark gap between itself and the first electrode. Therefore, it is possible to provide the discharge element that realizes a high production yield, a simple structure, and a cost reduction and a simple manufacturing method of the discharge element.
