Abstract
An airtight container manufacturing method includes the steps of exhausting an inside of a container through a through-hole provided in the container, arranging a plate member having, at its periphery, grooves penetrating the plate member in its plate thickness direction, on an outer surface of the exhausted container, so as to close up the through-hole, and providing a sealant on the plate member. In addition, a cover member covers the plate member via the sealant, and the container is sealed by closing the cover member on the plate member. In the sealing step the sealant is deformed and flows from the adjacent grooves to form a continuous shape and fill a space between the cover member and the outer surface of the container and along the periphery of the plate member.
