A phosphor 5 is structured with fluorescent particles 11, a coating film 12 which coats the fluorescent particles 11, and an insulation film 13 which further coats the coating film 12. The fluorescent particles 11 are formed by pulverizing a composite consisting of a fluorescent compound such as zinc sulfide (ZnS) and an auxiliary component such as manganese (Mn) added thereto. The coating film 12 consists of e.g. copper (Cu), and has a thickness of e.g. 2-20 nm to enhance the conductivity of electrons in the fluorescent particles 11. The insulation film 13 consists of e.g. high-permittivity organic polymer and has a thickness of e.g. 100 nm to increase the permittivity of the surface of the phosphor 5. <IMAGE>
