A method for producing a plasma display panel includes: (i) providing a front panel and a rear panel, the front panel being a panel wherein an electrode A, a dielectric layer A and a protective layer are formed on a substrate A, and the rear panel being a panel wherein an electrode B, a dielectric layer B, a barrier rib and a phosphor layer are formed on a substrate B; (ii) supplying a glass frit material onto a peripheral region of the substrate A or B to form a glass frit sealing member; (iii) opposing the front and rear panels with each other such that the glass frit sealing member is interposed therebetween; and (iv) heating the opposed front and rear panels to reach a softening point of the glass frit sealing member or a higher temperature than the softening point, while supplying a cleaning gas into a space formed between the opposed front and rear panels. Prior to the heating of step (iv), a gas is introduced into a space formed between the opposed front and rear panels, or a gas is exhausted from a space formed between the opposed front and rear panels.
