Abstract:
1. An airtight container manufacturing method, comprising 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; providing a sealant on the plate member; arranging a cover member so as to cover the plate member via the sealant; and sealing the container by closing the cover member on the plate member, wherein in the sealing step the sealant is deformed and flows from the adjacent grooves forming a continuous shape and filling a space between the cover member and the outer surface of the container and along the periphery of the plate member.
