PROBLEM TO BE SOLVED: To obtain a heat storage device in which the constitution of a heat storage container is simplified and furthermore the whole heat storage container can be prevented from upsizing and the weight thereof can be reduced.SOLUTION: A heat storage device 10 of the present invention includes a heat storage device body 30 and a heat exchanger 20. The heat storage device body 30 includes: a heat storage container 33 inside which a plurality of storage spaces 32 divided by partitions 31 and a common communication space 37 communicating with each of upper parts of the storage spaces 32 are formed; latent heat storage material 34 which is filled in each of the storage spaces 32 and is phase-changeable between solid and liquid; liquid surface coating material 35 covering the upper surface of each of the latent heat storage material 34; and a plurality of core generating devices 36 each of which is arranged inside each latent heat storage material 34 and changes the phase of the latent heat storage material 34 in a super cooled state from liquid to solid. Circulation liquid flows in the heat exchanger 20, which is arranged in such a manner that heat can be exchanged between the circulation liquid 20 and each of the latent heat storage material 34. |
