PROBLEM TO BE SOLVED: To provide an absorption refrigerating machine enabling to bleed non-condensed gas without lowering the performance of an absorber. SOLUTION: In the absorption refrigerating machine, a refrigerant heated and evaporated in an evaporator 10 is introduced into the absorber 20 and dissolved and absorbed in a lithium bromide solution in the absorber 20, while the lithium bromide solution diluted with the absorbed refrigerant is subjected to heat exchange with cooling water to be cooled. In the absorber 20, a plurality of heat transfer tubes 74 introducing and passing the cooling water are arranged regularly and also to be dense toward the front in the introducing direction of the evaporated refrigerant, and moreover the heat transfer pipes 74 positioned frontward in the direction of introduction, at least, are arranged in the shape of a grid when viewed as a section from the lengthwise direction, while a bleeding pipe 80 bleeding the non-condensed gas collected inside the absorber 20 is inserted into a pipe group D of the heat transfer pipes 74 arranged in the shape of the grid along the direction of arrangement of the pipes 74.
