Abstract
A discharge electrode for a gas discharge device has pin-shaped electrodes which are effectively cooled in the gas flow and which promote a stable glow-discharge. The pin-shaped electrodes are made from a wire member which is curled at its end. An extension portion of the electrodes extends a predetermined length from the curled end, and is bent in an approximately L-shape to form a post position. The pin-shaped electrode is disposed in the gas flow so that the extension portion is orthogonal to the gas flow.
