Abstract
An airtight container manufacturing method includes the steps of exhausting an inside of a container through a through-hole provided in the container, and arranging a spacer member along a periphery of the through-hole on an outer surface of the container. Additional steps include arranging a plate member having, at its periphery, grooves penetrating the plate member in its plate thickness direction so that a sealant will flow from the grooves to a side surface of the spacer member, with the spacer member and the through-hole covered by the plate member, and a gap is formed along the side surface of the spacer member between the plate member and the outer surface of the container, and sealing the container by arranging a cover member to cover the plate member via a sealant. The sealing step includes hardening the sealant after deforming the sealant by pressing the plate member with the cover member so that the sealant flows between the cover member and the outer surface of the container via the grooves and the gap is infilled with the sealant.
