Abstract

PURPOSE:To reduce the cost without increasing the number of parts and the assembling man power, by providing a conductive film on a glass supporter while to enable the control of the spark discharge and the stray electron. CONSTITUTION:A conductive film 9 made of SnO2 is coated in circular while crossing with the axial direction at a portion of outer-circumferential face facing with the outer-cirumferential section of G2 electrode 4 of an insulated glass 6. Here said circular conductive film 9 is coated with the film depth electrically connectable with the supporting section 4a of G2 electrode 4. The conductive film 9 can be easily formed through deposition while using the aparture when forming the insulated glass 6.
