The invention belongs to the technical field of heat preservation, and provides a cold storage heat insulation plate which comprises a cold storage layer and a heat insulation layer. The cold storage layers comprise the first cold storage layer to the Nth cold storage layer, cold supplement of liquefied gas is achieved, and heat transfer is slowed down. In the first cold storage layer to the Nth cold storage layer, the ith cold storage layer comprises an ith cold storage material, the ith cold storage material has an ith phase-change temperature, the ith phase-change temperature is smaller than an (i + 1) th phase-change temperature, N is an integer larger than 1, i is a positive integer smaller than or equal to N, and N is an integer larger than 1; the multi-level supplement of the liquefied gas cooling capacity and the effective regulation and control of the liquefied gas cooling capacity release rate are realized; the heat insulation layers are located between the first cold storage layer and the Nth cold storage layer and comprise the first heat insulation layer to the Mth heat insulation layer, M is a positive integer smaller than N. The heat insulation plate has the good heat insulation effect, and the overall size of the cold storage heat insulation plate is effectively reduced. The invention further provides a liquefied gas storage device comprising the cold storage heat insulation plate and a transport ship.
