PURPOSE:To form a sealing member capable of sealing at a low temperature with high reliability of sealing characteristic in an excellent mass production by glazing a low melting point glass on one side surface of a supporting member and plating gold on the other side surface. CONSTITUTION:A supporting member 12 made of ceramic formed in a frame shape is formed at a sealing member 10. A metallized layer 14 made of metal such as tungsten, molybdenum or the like is baked on the lower surface of the member 12, a nickel is plated on the layer 14, and a low melting point glass 20 is glazed on the upper surface of the member 12. This glass 20 is coated and glazed on the surface after plated. In order to form a low melting point glass 20 layer, low melting glass powder is formed in a paste state with acryl resin and nitrocellulose as an organic binder and terpineol or the like as a solvent, and coated by a screen printing on the upper surface of the member 12. Subsequently, it is dried at 80-150 deg.C, and then glazed at 300-450 deg.C. |
