SOLUTION: This arrester device, which connects a series circuit of the voltage dependent nonlinear arrester element 21 and an open discharging gap 31 between the power supply line L1 and the earth E, sets the operation starting voltage of the arrester element 21 to be lower than a peak value of a voltage between the power supply line and the earth, and to be higher than an arc voltage in discharge of the discharging gap 31, and sets a discharge starting voltage of the discharging gap 31 to be higher than the peak value of the voltage between the power supply line and the earth. Thereby the discharge voltage of the arrester element 21 to the lightning surge is set to be low. The open discharging gap 31 self-restores by a leakage current even in a case of dew condensation.
