PURPOSE:To perform highly reliable interlayer insulation by exposing the air bubble in a film by abrading the surface of the insulating glass film in the lower layer, then burying the hole with the upper layer glass. CONSTITUTION:The surface layer 12 is removed by abrading the surface of the first insulating glass layer 6a. Then, the upper side 8 of the air bubble 7 in the film is removed, and the bubble 7 is exposed to the surface of the layer. When the second insulating glass layer 6b is layered, the air in the bubble is exhausted and the hole is filled with the glass during the printing. If a conductor 5 is formed thereon, the short circuits or leakage is not caused between the upper conductor 5 and the lower conductor 2. |
