Abstract

To provide an antistatic device having a low capacitance, good discharge characteristics, and small variations in the discharge characteristics. In a so-called gap-type antistatic device in which a space between a pair of opposing electrodes is filled with an electrostatic protection material, a discharge inducing portion has protrusions protruding from interfaces between the opposing electrodes and the insulation substrates toward the insulation substrates and has a shape protruding on both sides of the insulation substrates. The relationship among the gap distance between the electrodes, the thicknesses of the opposing electrodes, and the protrusions of the discharge inducing portion is controlled under specific conditions.
