To realize a plasma display panel having display performances of high precision and high brightness with low power consumption, after formation of base film (91), a metal oxide paste made of metal oxide particles, an organic component including a photopolymerization initiator, a water-soluble cellulose derivative, and a photopolymerization monomer, and a diluting solvent is applied. By exposing, developing, and firing the paste film, agglomerated particles as a plurality of metal oxide particles agglomerated are formed so as to be attached on base film (91). The content of the metal oxide particles included in the metal oxide paste is 1.5% by volume or less.
