Abstract
The present invention provides an arrester in which energy during discharge is not concentrated in one point and which has good responsiveness to overvoltage. The arrester is provided with an energy absorber 3 that absorbs energy when a lightning strike occurs, and a pair of conductive electrodes 1 and 2. Between the pair of conductive electrodes 1 and 2, two air gaps 9 are formed in series, between the conductive electrode 1 and the energy absorber 3, and between the conductive electrode 2 and the energy absorber 3. The two air gaps 9 include planer gaps.
