PROBLEM TO BE SOLVED: To provide an absorption type heat accumulator capable of improving absorption performance. SOLUTION: This absorption type heat accumulator is provided with evaporators 4, 5 of a plurality of stages for evaporating refrigerant liquid A, heat exchange flow passages 6 provided in the evaporators 4, 5 at each stage to receive supply of heating fluid and heat the refrigerant liquid A, absorbers 7, 8 of a plurality of stages provided by corresponding to the evaporators 4, 5 at each stage to absorb evaporating refrigerant gasified in the evaporators 4, 5 at each stage by cooling, and heat exchange flow passages 9 provided in the absorbers 7, 8 at the plurality of stages to receive supply of cooling fluid and cool an absorption material B. The heat exchange flow passages 9 in the absorbers 7, 8 at the plurality of stages and a hot heat source 3 are mutually connected in series or in parallel to form a circulation path X of cooling fluid. A circulation path Y of heating fluid for connecting the heat exchange flow passages 6 in the evaporators 4, 5 at the plurality of stages with a cold heat source 2 in series is formed separately from the circulation path X.
