The invention relates to a spark gap comprising a number of series-connected individual spark gaps which are placed in a stack arrangement, which are spaced apart from each other by insulating material discs and are provided with a spring contact, the individual spark gaps including ring-shaped or disc-shaped electrodes, and further comprising control elements for influencing the voltage distribution over the stack arrangement. According to the invention the ring-shaped or disc-shaped electrodes required to form one of the respective individual spark gaps are each inserted into an insulating body and held by same in a centered manner. The respective insulating material discs are located between and fixed by the insulating bodies. A recess is provided inside the insulating body to receive and center the electrodes, whose shape is complementary relative to the contour of the respective electrode, wherein the recess comprises on the inner circumference at least partially elastic, resilient centering projections or centering noses.
