When a PDP 10 is produced by superposing, and fixing, a front plate 16 and a rear plate 18 on, and to, each other, a sheet member 20 including an X wiring layer 36 and a Y wiring layer 40 is fixed to the front plate 16 or the rear plate 18, so that X electrodes 46 and Y electrodes 48 are provided in respective discharge spaces 24. Thus, the X electrodes 46 and the Y electrodes 48 can be assembled with the front and rear plates 16, 18, by just placing the sheet member 20 between the two plates 16, 18. Therefore, in the PDP 10, the front plate 16, the rear plate 18, and the discharge electrodes 46, 48 are free of distortions resulting from a heat treatment that would otherwise be carried out to form the electrodes.
