摘要：
An electrostatic discharge (ESD) protector includes a ceramic body having a cavity provided therein, and two discharge electrodes facing each other across the cavity. The discharge electrodes are made of metal containing more than 80 wt.% of tungsten. The discharge electrodes contain not more than 2.0 atomic % of tungsten bonded to oxygen to a total amount of tungsten contained in the discharge electrodes. This ESD protector does not cause a short-circuiting even upon having high-voltage static electricity applied to the discharge electrodes repetitively, thus having high reliability.
