PROBLEM TO BE SOLVED: To provide a heat storage device capable of reducing the number of pieces of components by simplifying a connecting structure of a heat conductive pipe in a heat storage tank and its external pipe, and simplifying the manufacturing and assembling work and reducing the cost. SOLUTION: A heat storage material is accommodated in the heat storage tank 22, and the heat conductive pipe 24 and an electric heater 26 are buried in a heat storage material. The heat conductive pipe 24 is formed from one pipe material with the meander shape in side and plan views. The connecting structure of the external pipe to an inlet and an outlet of the heat conductive pipe 24 is simplified, the number of pieces of components is reduced, and the manufacturing and assembling work can be easily performed.
