PROBLEM TO BE SOLVED: To improve a heat-generation efficiency of hydration reaction when the hydration reaction and decomposition reaction are performed repeatedly in a heat storage device. SOLUTION: This heat storage device includes a water chamber 10, a reactor 20 housing alkaline earth metallic oxides, a first passage 40 for circulating water, a first control valve 42 for opening/closing the first passage 40, a heat source 120, an in-water chamber temperature measuring means 12 for measuring a temperature in the water chamber 10, an in-reactor temperature measuring means 22 for measuring a temperature in the reactor 20, a reaction speed obtaining means 22 for obtaining the reaction speed of the hydration reaction, and a control means 60 for controlling opening/closing of the first control valve 42. The control means 60 raises the temperature in the reactor 20 and/or the temperature in the water chamber 10 when the reaction speed obtained by the reaction speed obtaining means 22 is smaller than a prescribed value, and then, opens the first control valve 42, thereby inducing the hydration reaction.
