To provide a washing/drying machine by which the time needed for washing and drying can be reduced by reducing the washing time by enhancing washing capacity.

The washing/drying machine according to the present invention has: a water tank disposed in an outer frame casing body; a rotatable washing/drying tank disposed in the washing tank storing the laundry; a compressor compressing a coolant; a radiator radiating the heat of the compressed coolant; a control valve reducing the pressure of the compressed coolant; a heat pump device including a heat absorbing device in which the coolant which is depressurized to reach a low pressure deprives the surrounding of the heat; a washing/drying tank; an air side radiator for drying; and an air flowing channel for drying through which the air for drying circulating through the heat absorbing device flows. The washing water heated by the radiator is sprayed to the laundry in the washing/drying tank in washing/drying operation.
