用いて封着する方法が行われていた。 In conventional flat display tubes, for example, when a boat-shaped transparent glass container is sealed to a flat insulating substrate,
Alternatively, in the case of sealing two flat plates through a spacer, paste-like low-melting frit glass melted with an organic binder or the like is screen printed in a predetermined shape on the object to be sealed, or compressed and press-shaped into a predetermined shape. Using a glass tablet, or as shown in Japanese Patent Application Laid-Open No. 15750/1983, a metal mesh having a coefficient of thermal expansion equal to the thermal expansion coefficient of the object to be sealed is covered with fritted glass, and then the fritted glass binder is dried and pre-baked. A method of sealing using a sealed sealing material was used.

いつた欠点があつた。 However, the above-mentioned method of applying and sealing the paste-like low melting point fritted glass to the surface to be sealed by screen printing makes screen printing difficult depending on the shape of the object to be coated, and also because of the low melting point glass paste. Since calcining requires firing in an oxidizing atmosphere, the object to be coated includes parts that would be significantly damaged by firing in an oxidizing atmosphere, making the calcining process itself difficult. Furthermore, the method of using a glass tablet compressed and pressed into a predetermined shape as a sealant has drawbacks such as the glass tablet being brittle and difficult to handle. Furthermore, the method of using a sealing material in which a metal mesh matched to the coefficient of thermal expansion of the material to be sealed is covered with frit glass requires punching out or etching the metal used as the core into a mesh shape, resulting in high costs. Furthermore, when this sealing material was used in the sealing part of the display tube, there was a drawback that the insulation of the lead wire part of the display tube was poor.

A pipe and a method for manufacturing the same are provided.
