A surge arrester includes an insulator having a first insulator end and an opposite second insulator end, at least one first electric arc electrode attached in the region of the first insulator end, at least one second electric arc electrode attached in the region of the second insulator end, a fixing element made of electrically non-conductive material for mounting the surge protector on an external support, and at least one dish-shaped element to which the first electric arc electrode is assigned and the dish side wall of which at least partially laterally encloses the first electric arc electrode. The fixing element is attached laterally to the dish side wall of the dish-shaped element.
