A static neutralizer which emits ions without emitting light to the environment. The static neutralizer includes a body of insulating light absorbing material, having a cavity therein, with points of ion emitters located in the cavity. A passage leads from the cavity to the exterior, permitting flow of ions from the body and preventing passage of light from the ionizing points to the exterior. A metal sleeve surrounds the insulating material body with a peripheral edge of the metal band and the ionizing points preferably lying in a common plane. A source of electric potential, preferably alternating, is connected to the ion emitters, and the metal sleeve is connected to ground. Preferably, the connections are provided by a shielded cable having an inner conductor connected to the ion emitters, an outer, flexible woven wire shield connected to the metal band, and a light impervious, insulating layer on the exterior of the woven shield. The ion emitters are needles which penetrate the body and the inner conductor.
