PROBLEM TO BE SOLVED: To provide a chemical heat storage device having high durability and capable of suppressing lowering of heat storage amount even when heat is repeatedly injected and extracted. SOLUTION: This chemical heat storage device includes a heat reservoir storing container 20 for storing a heat reservoir 22 including a chemical heat storage material, a heat injecting device 32 for injecting heat to the heat reservoir 22, a heat extracting device 34 for extracting the heat from the heat reservoir 22, a water storing container 40 for storing the water 42, a steam supply-discharge device 50 for transferring and receiving the steam between the heat reservoir storing container 20 and the water storing container 40, a first temperature measuring device 62 for measuring a temperature of the heat reservoir 22, a second temperature measuring device 64 for measuring a temperature of the water 42, and a control device 70 for controlling the steam supply-discharge device 50 according to the temperature of the heat reservoir 22 and the temperature of the water 42, and the control device 70 includes a dewatering ratio adjusting means for controlling a dewatering ratio of the chemical heat storage material within 80-90 wt.%, and/or a hydration ratio adjusting means for controlling a hydration ratio of the chemical heat storage material within 85-95%.
