Light-emitting windows are provided in the region of each anode facing the cathode constituting the anode and electrode pair at equal pitches based on the center of gravity of the opening area of each light-emitting window, and at or near the boundary between each anode. A light emitting window for the opposing cathode is defined by opposing ends of two adjacent anodes, and a center of gravity of the area of a portion of the defined light emitting window facing the cathode and another adjacent to the light emitting window are defined. A gas discharge light emitting device characterized in that the distance between the light emitting window and the center of gravity is equal to the pitch. (2) An optical print head using the gas discharge light emitting device according to claim 1 as a light source.
