PROBLEM TO BE SOLVED: To provide a heat pump device which downsizes a refrigeration device by making a contour of an oil separator smaller and does not cause reduction in capacity although a compressor is used for a long term. SOLUTION: The heat pump device includes: a heat pump circuit formed of the compressor 21, a radiator 23, a decompression means 24, and an evaporator 25 for discharging refrigerant compressed by a compression mechanism part in a sealed container with lubrication oil enclosed therein from a discharge port provided for the sealed container to the outside of the sealed container; an oil separator 27 for separating the lubrication oil from the refrigerant in the heat pump circuit; and an oil feeding part 30 for returning the lubrication oil separated by the oil separator 27 to an intake side of the compressor 21. The oil feeding part 30 is arranged with an oil absorber 31 for absorbing/desorbing the lubrication oil. The lubrication oil accumulated in the oil separator 27 can be returned to the inside of the compressor 21 by absorption force of the oil absorber 31. COPYRIGHT: (C)2010,JPO&INPIT
