Disclosed is a plasma display panel comprising a front plate wherein a dielectric layer is so formed as to cover a display electrode formed on a front glass substrate and a protective layer is formed on the dielectric layer, and a back plate so arranged as to face the front plate so that a discharge space is formed therebetween. The back plate is provided with an address electrode lying in the direction intersecting the display electrode and a partition wall which divides the discharge space. The protective layer is obtained by forming a base film on the dielectric layer, and having agglomerated particles, wherein a plurality of crystal particles composed of a metal oxide are agglomerated, adhere to the base film in such a manner that the agglomerated particles are distributed all over the base film. The number of the agglomerated particles adhering the base film is set at not less than 45 but not more than 350 per 10,000 μm2 of the base film.
