A method for manufacturing a plasma display panel is provided. The method includes making a front substrate and a rear substrate individually and applying a low melting point glass paste including non-porous bead onto a portion of the front substrate or the rear substrate so that the applied low melting point glass paste forms a frame-like shape having a height greater than that of the structural member. The method includes assembling the front substrate and the rear substrate in a face-to-face relation with each other and burning the applied low melting point glass paste while vacuuming a discharge gas space between the front substrate and the rear substrate so as to seal the front substrate and the rear substrate.

A screen mask includes a screen mesh with a tensioning force of 196 to 392 N/mm; a tension mesh with a tensioning force of 49 to 98 N/mm; a resin plate (fixing part) arranged so as to surround the outer periphery of the screen mesh for fixing a part of the tension mesh with a tensioning force of 392 to 980 N/mm; and a screen frame. A length Ls of the screen mesh in a first direction intersecting a direction in which a squeegee squeegees on the screen mesh when performing a screen printing is 0.6 to 0.9 times a length Lt of the tension mesh in the first direction, a length Lk of the resin plate, the length Ls, and the length Lt in the first direction satisfy a relationship Lk=a(Lt+Ls)/2, where 'a' is a coefficient in a range of 0.5 to 1.2.
