PROBLEM TO BE SOLVED: To provide a heat storage device capable of shortening crystallization time and improving a heat drawing speed.SOLUTION: A heat storage device includes: a heat storage vessel 11 storing therein a latent heat storage material 10 that can store heat in an over-cooled state; a trigger unit 13 releasing the over-cooled state of the latent heat storage material 10; a heat source-side heat pipe 17 and a heat use-side heat pipe 15; and fins 21 and 23 connected to the heat source-side heat pipe 17 and the heat use-side heat pipe 15, and dividing an interior of the heat storage vessel 11 into a plurality of regions S. Communication ports 21A communicating the adjacent regions S are provided in the respective fins 21, and communication ports 23A and 23B communicating the adjacent regions S are provided in the respective fins 23. The regions S in which the trigger unit 13 is provided are communicated with the other regions S via the communication ports 21A, 23A, and 23B. |
