Abstract
A funnel-shaped chip tube and a tubular-shaped press frit are prepared. After the chip tube is disposed on a major surface of a substrate so that the center axis of an exhaust hole provided in the substrate of a sealed container body and the center axis of the chip tube may substantially coincide with each other, the press frit is so disposed as to be located on a surface of an opening portion. After that, by heating the whole device, the press frit is heated and melted, to provide a sealing member contiguously from an outer-rim outside portion of the flare-shaped opening portion of the chip tube to a portion of a tubular portion beyond a boundary.
