PROBLEM TO BE SOLVED: To provide an efficient multi-stage absorption refrigerating machine provided with a compact and inexpensive multi-stage evaporating/absorbing cycle. SOLUTION: In this absorption refrigerating machine having a regenerator G, a condenser C and a unit 1 of an evaporator and an absorber, the unit 1 is provided with an evaporator element 5H for exchanging heat between cold water flowing inside a heating surface and refrigerant liquid flowing outside the heating surface from upper and an absorbing element 5A for exchanging heat between the cooling water flowing inside the heating surface and the absorbing liquid flowing outside the heating surface from upper. The elements 5H and 5A are arranged each other in the horizontal direction with the predetermined interval, and housed in a sealed container. In the unit 1, the housing sealed container is divided into a plurality of hydraulic pressure areas by partitions. In each of the plurality of hydraulic pressure areas divided in the unit 1, the elements 5H and 5A can be arranged in several stages in the vertical direction, and the elements 5H and 5A can be formed of a plate heat exchanger or a tubular heat transfer body.
