PROBLEM TO BE SOLVED: To provide a production method for obtaining a PDP excellent in panel characteristics. SOLUTION: The method for producing a PDP includes: (i) a step to prepare a front panel and a rear panel; (ii) a step to supply a glass frit material onto a peripheral region of a substrate A of the front panel or a substrate B of the rear panel to form a glass frit sealing member; (iii) a step to arrange the front and rear panels to be opposed with each other such that the glass frit sealing member is interposed therebetween; and (iv) a step to heat the front and rear panels to reach a softening point of the sealing member or a higher temperature than the softening point once so that the front panel and the rear panel are sealed, while supplying a cleaning gas into a space formed between the front and rear panels during the start of the heating process through the reaching to the softening point of the sealing point. Prior to the start of heating treatment in the step (iv), gas is introduced into a space formed between the front and rear panels, or gas is exhausted from a space formed between the front and rear panels, and a pressure difference before and after the gas introduction or gas exhaustion is recognized.
