Abstract

[Problem] To provide an electrostatic surge suppressor having improved durability with repeated use and excellent discharge properties. [Solution] Provided is an electrostatic surge suppressor 100 that comprises an insulating laminate 11, a pair of discharge electrodes 12 and 13 inside the insulating laminate 11, and a discharge inducing part 14 disposed between the discharge electrodes and around the terminals of the discharge electrodes, wherein insulating layers 15 and 16 containing a glass are disposed on the surfaces of the discharge electrodes. By disposing the insulating layers containing a glass on the surfaces of the discharge electrodes, the current that is generated by discharge is prevented from flowing to the discharge-inducing part of the conductive inorganic material in the discharge electrodes.

Description

technical field [0001] The present invention relates to an electrostatic countermeasure device, and particularly relates to an electrostatic countermeasure device useful for use in a high-speed transmission system or in combination with a common mode filter. Background technique [0002] In recent years, the miniaturization and high performance of electronic devices have rapidly progressed. In addition, as represented by high-speed transmission systems such as antenna circuits such as mobile phones, RF modules, USB2.0 and USB3.0 or S-ATA2, HDMI, etc., the increase in transmission speed and the low drive voltage of circuit components used development is remarkable. With miniaturization of electronic equipment and reduction in driving voltage of circuit elements, the withstand voltage of electronic components used in electronic equipment decreases. Therefore, it is an important technical issue to protect electronic components from overvoltage typified by static electricity p...
