PROBLEM TO BE SOLVED: To provide a liquefied gas storage device in which the generation of offgas is suppressed, a vehicle having the liquefied gas storage device, and a method of storing liquefied gas. SOLUTION: This liquefied gas storage device 1 comprises a vacuum tank 4, a liquefied gas storage tank 3 installed in the vacuum tank 4 for storing the liquefied gas 70, and a support member 5 for supporting the lower part of the liquefied gas storage tank 3 on the vacuum tank 4. The liquefied gas storage device does not comprise a support member for supporting the portion of the liquefied gas storage tank 3 other than the lower part on the vacuum tank 4. Since a heat coming from the outside into the device is concentrated to the lower part of the liquefied gas storage tank 3, the heat is hard to be used as the latent heat of vaporization of the liquefied gas 70. Consequently, the generation of boiloff gas can be suppressed. COPYRIGHT: (C)2009,JPO&INPIT
