The present invention is substantially free of lead and bismuth, which is environmentally friendly, safe and cost-friendly, has good moisture resistance, and is capable of softening at low temperatures that do not corrode electrode wirings such as silver, copper, and aluminum. To provide. Moreover, the sealing material, wiring material, structural material, and optical material which used this glass composition are provided. Furthermore, an electronic device such as an image display device such as a plasma display panel using these materials, a sheath heater, a solar cell element, or the like is provided.n n n For this purpose, the glass composition is substantially free of lead and bismuth, and contains at least vanadium oxide and phosphorus oxide as main components, the specific resistance at 25 ° C is 10 9 Ωcm or more and the softening point is 500 ° C or less. Moreover, as a component, it contains manganese oxide and barium oxide. Moreover, it is preferable to contain any of oxides of an alkali metal, antimony, tellurium, zinc, silicon, aluminum, niobium, rare earth elements, iron, tungsten and molybdenum. |
