To provide a heat pump device that reduces the propagation of vibration to an evaporator to achieve a product with reduced noise.
A heat pump device includes: a refrigerant circuit in which a compressor 4, a radiator 5, a pressure reducing means 6, and an evaporator 7 are sequentially connected; a liquid-gas heat exchanger 16 for exchanging heat between a refrigerant from a refrigerant outlet side of the radiator 5 to a refrigerant inlet side of the pressure reducing means 6, and a refrigerant from a refrigerant outlet side of the evaporator 7 to a suction part of the compressor 4; and a muffler 17 disposed in a part of the refrigerant circuit from the liquid-gas heat exchanger 16 to the intake part of the compressor 4. A pipe length L1 from the muffler 17 to the intake part of the compressor 4 is longer than a pipe length L2 from the liquid-gas heat exchanger 16 to the muffler 17.
