PROBLEM TO BE SOLVED: To provide a paste composition which has a low firing shrinkage factor and maintains high mechanical strength after being fired, an inorganic film, and a partition member for a plasma display panel. SOLUTION: The paste composition contains a mixed inorganic powder, obtained by mixing a glass powder and a filler powder having a softening temperature higher than that of the glass powder in a specific ratio. The mixed inorganic powder comprises 65-35 mass% glass powder and 35-65 mass% filler powder. The glass powder and the filler powder are characterized in that when the particle size frequency at the peak particle size P (μm) in a particle size-particle size frequency curve of the glass powder is defined as X(%) and the particle size frequency at the peak particle size P (μm) in a particle size-particle size frequency curve of the mixed inorganic powder is defined as Y(%), 1-(Y/X) is not lower than 0.60. The inorganic film is obtained by firing the composition, and the partition member for the plasma display panel includes the inorganic film. COPYRIGHT: (C)2007,JPO&INPIT
