To provide a sealed and thermally-insulating tank for storing a low-temperature liquefied gas to prevent flow of an inert gas from not reaching a confined space.SOLUTION: A sealed and thermally insulating tank has a bottom panel (17), the bottom panel is constituted to be kept into contact with a support wall by sealant beads (60, 61) disposed between the support wall and the bottom panel, the sealant beads are disposed in the form of at least one closed outline defining at least one confined space between the support wall and the bottom panel, and the bottom panel has at least one through passage (51) leading into the confined space to circulate a gas between the confined space and an internal space of a heat insulating box portion (11).SELECTED DRAWING: Figure 4 【課題】閉鎖空間に不活性ガスの流れが行き届かなくなることを防止する低温液化ガスを貯蔵するための密閉断熱タンクを提供する。【解決手段】密閉断熱タンクは底パネル（１７）を有し、底パネルは支持壁と底パネルの間に配置された封止玉縁（６０，６１）によって支持壁に当接するよう構成され、封止玉縁は、支持壁と底パネルの間に少なくとも１つの閉鎖空間を定める少なくとも１つの閉じた輪郭の形で配置され、底パネルは、閉鎖空間と断熱ボックス部（１１）の内部空間との間でガスを循環させるために閉鎖空間に至るよう構成された少なくとも１つの貫通通路（５１）を備える。【選択図】図４
