When welding a window glass to a cap, the cap body is formed into a predetermined shape, an oxide film is deposited on the inner wall surface of the cap body, a low melting point glass is applied, a glaze treatment is applied, and the window glass is welded. Weld. Oxide film deposition treatment, glaze treatment, and window glass welding are all done by heat treatment. The reason why an oxide film is formed on the inner wall of the cap body is that the window glass cannot be welded simply by applying low-melting glass to the cap body, and the glass is welded by the wettability of the glass to the oxide film.
