To provide a heat pump type hot water supply device reducing a discharge pressure of a compressor and improving COP.

A typical constitution of this heat pump type hot water supply device comprises the compressor 102, an expansion valve 104, an evaporator 106, a plurality of radiators (first radiator 110, second radiator 112) exchanging heat between refrigerants of various temperature zone and hot water of a plurality of systems, and a plurality of heat storage tanks (high-temperature heat storage tank 120, intermediate-temperature heat storage tank 122) for storing the hot water of the plurality of systems heated to various temperature zones, and a supercritical cycle to bring the refrigerant in a supercritical state, is performed between a compression process and a radiation process.
