To provide a heat storage tank equipped with a sealed vessel capable of certainly absorbing a volume change of a latent heat storing material.
A heat storage unit 40 of this heat storage tank is equipped with the sealed vessel 43. The latent heat storing material 47 and a filler gas are encapsulated in the vessel 43. The vessel 43 is furnished with a heat storing material reservation part 44, a gas reservation part 44, and a communication part 46. The side wall 61 of the gas reservation part 45 is formed in bellows capable of expanding and contracting. With the side wall 61 only the filler gas is in contact, and the latent heat storing material 47 is not in contact. When the material 47 in the vessel 43 is melted, the side wall 61 elongates to increase the capacity of the vessel 43. When on the other hand, the latent heat storing material 47 is solidified, the side wall 61 is contracted so as to decrease the capacity of the vessel 43.
