A heat storage device capable of improving heat exchange efficiency and response speed in a heating mode for heating an object to be heated. A first container 11 that contains a first reactant A in a solid state, a second container 12 that contains a second reactant B in a liquid state, and a heating unit that heats an object F to be heated by reaction heat. 13, a mixing unit 14 for mixing the first reactant A and the second reactant B, a first passage 41 for guiding the second reactant B contained in the second container 12 to the mixing unit 14, and the mixing unit 14 The second passage 42 that guides the mixture mixed in the heating section 13, the third passage 43 that guides the second reactant B from the first container 11 to the second container 12, and the first to third passages 41 to 43. The first to third opening / closing means 51 to 53 for opening and closing and the control unit 7 for controlling the operation of the first to third opening / closing means 51 to 53 are provided.
