A liquefied gas storage tank includes: an inner shell storing a liquefied gas; an outer shell forming a vacuum space between the inner shell and the outer shell; and a fail-safe thermal insulating layer covering an outer side surface of the outer shell. According to this configuration, the fail-safe thermal insulating layer is not disposed in the vacuum space. This makes it possible to suppress the degradation over time of the degree of vacuum in the vacuum space.
