PROBLEM TO BE SOLVED: To provide a dielectric structure of a plasma display panel, capable of obtaining a dielectric layer having excellent transparency and a high withstand voltage, wherein yellowing is not easily caused by reaction with a silver electrode. SOLUTION: This dielectric structure of the plasma display panel has a lower dielectric layer to coat an electrode and an upper dielectric layer formed on the lower dielectric layer, and the upper dielectric layer is made of glass containing 25-55% PbO, 10-40% B<SB>2</SB>O<SB>3</SB>, 1-15% SiO<SB>2</SB>, 5-30% BaO, 3-35% ZnO, 0-10% Al<SB>2</SB>O<SB>3</SB>, 0-20% CaO+MgO+SrO+Bi<SB>2</SB>O<SB>3</SB>, and 0-10% TiO<SB>2</SB>+ZrO<SB>2</SB>+SnO<SB>2</SB>, in a mass percentage.
