A heat pump hot water supply device where a heat pump cycle for hot water supply can be used for cooling and heating (air conditioning) and in which sufficient temperature and quantity of hot water supply are obtained when hot water is provided along with heating. The hot water supply device has a CO2 cycle (1) where CO2 refrigerant is circulated and also has an R410A cycle (2) where R410A refrigerant is circulated; a water heat exchanger (32) for performing heat exchange between water and the CO2 refrigerant and/or the R410A refrigerant. The R410A cycle (2) has a circulation route (20) passing through the water heat exchanger (32), a circulation route (40) passing through an indoor-air heat exchanger (4) for exchanging heat between the R410A refrigerant and indoor air, and a four-way valve (24) for changing the direction of circulation of the R410A refrigerant in the R410A cycle (2).
