A lighting arrester of a simple structure facilitates connection of same to a coaxial cable or the like, affording reduced connection costs while providing, optionally, fail-safe and vent-safe functions. A central electrode of the light arrester has a discharging section and a pair of lead terminals extending from opposite ends of the discharging section, each for connection to a signal line. A tubular outer electrode, for connection to an earth line, has an interior space accommodating the central electrode therein. A pair of insulating holders are received at opposite ends of the tubular electrode and the lead terminals extend through and are held thereby for positioning the central electrode within the interior space of the outer electrode, isolating the discharging section from the inner circumference of the outer electrode by a predetermined gap therebetween, the terminals extending outwardly from the outer surfaces of the respective insulating holders.
