PROBLEM TO BE SOLVED: To provide a device for desalting salt water by using solar heat, decreasing electric power consumption extremely and being driven by only solar batteries or by solar batteries and storage batteries to eliminate the need for external electric power. SOLUTION: In a device for desalting salt water, using a heat collector 9, which collects solar heat and through which a heat transfer medium d passes, and a heat storage tank 11, which stores cooled heat in a heat storage medium e, as a heat source device, and having heat exchangers for evaporative concentrators 5, 6, 7 and heat exchanger for a condenser 12, a piping system 36, 37, 38 through which a heat transfer medium d circulates is installed between the heat collector 9 and the heat exchanger for the evaporative concentrator 5, the heat exchanger for the condenser 12 is installed in the heat storage tank 11, and a pump for the heat transfer medium, driven by solar batteries, may be installed in the piping system circulating between the heat collector 9 and the heat exchanger for the evaporative concentrator 5.
