A pair of thick first electrodes (2) are formed on an upper surface of alumina substrate (1) are formed with material having a low specific resistance. Thin second electrodes (3) that are positioned between first electrodes (2) and made of material having a high melting point are formed in a thin state. A gap (4) is formed between the second electrodes (3). First electrodes (2) forming connection electrodes are prevented from producing heat and protected from damage. The width of the gap between second electrodes (3) is narrow and accurate. This provides an electrostatic discharge (ESD) protector that is resistant to repetitive application of static electricity, reduces a peak voltage, and has a stable characteristic suppressing electrostatic discharge.
