PROBLEM TO BE SOLVED: To provide a coaxial arrester device, capable of shallowing depth of a through-hole and a recess portion in comparison with a conventional coaxial arrester device, in which a gap-type arrester and a varistor are arranged together in a single hole formed in an external conductor, to make an outside diameter of the external conductor reducible and consequently miniaturize the coaxial arrester device. SOLUTION: In the coaxial arrester device A consisting of a central conductor 1 and an external conductor 2 arranged coaxially in the central conductor, the through-hole 21 and the recess portion 22, are formed in the external conductor 2, a gap-type arrester 5 is disposed in the through-hole, and the varistor 9 is disposed in the recess portion 22. |
