PROBLEM TO BE SOLVED: To reduce a volume to be occupied by a duct in a storage vessel while reducing the number of holes formed in the storage vessel, where heat medium flows. SOLUTION: The liquefied gas storage vessel 1 has a heat pipe 2 for heating a liquid phase b of liquefied gas in the storage vessel 1. The heat pipe 2 has one cylindrical body in which operating liquid 11 moves in both directions from the side of a heat receiving part 3 to the side of a heat releasing part 12 and from the side of the heat releasing part 12 to the side of the heat receiving part 3 to transmit the heat of a heat source machine 6 to the liquid phase b with the movement. In the case of providing one heat pipe 2, one hole is only formed in the storage vessel 1. The heat pipe 2 has a compact volume, therefore preventing a reduction in the storage amount of the liquefied gas without impairing a degree of freedom in selecting the installation layout.
