Overvoltage protecting element

摘要

An overvoltage protecting element of the invention has a pair of main electrodes, the discharging surfaces of which oppose each other with a gap therebetween in a cylindrical body of an insulator, and a conductive member which is formed on the inner wall surface of the cylindrical body to oppose the main electrodes with a gap therebetween, and a plurality of extended parts of which extending in the circumferential direction of the cylindrical body being connected in the axial direction of the cylindrical body. The main electrodes and the conductive member are electrically connected to each other by capacitive coupling.
