Claim:
1. A sealing material, comprising: a low melting point glass powder which is boron oxide-zinc oxide-vanadium oxide glass powder, or vanadium oxide-zinc oxide-barium oxide glass powder; a cellulose resin; a solvent; and a functional material comprising an inorganic powder whose surface has a modified layer, wherein the inorganic powder comprises any one or more of aluminum oxide, magnesium oxide, diiron trioxide, calcium oxide, potassium oxide, sodium oxide and lithium oxide; and the modified layer is generated by a reaction of a dianhydride and a diamine, wherein the sealing material further comprises an additive(s), and without calculating the mass of the modified layer in the functional material, the mass percentages of the components in the sealing material are: the low melting point glass powder: 10 to 50%; the cellulose resin: 10 to 30%; the solvent: 15 to 75%; and the additive(s): 0.2 to 5%.
