PROBLEM TO BE SOLVED: To provide an air conditioner for an electrically-driven vehicle capable of effectively utilizing a heat exchanger for batteries in a battery pack and a heater for heating, and further to provide an air conditioner for an electrically driven vehicle capable of securing indoor heating performance by a heat pump system even at a cryogenic temperature.SOLUTION: An air conditioner for an electrically-driven vehicle comprises a battery cooling circuit 3 in parallel with a refrigerant circuit passing through expansion means 14 and an indoor heat exchanger 12 in a cooling cycle of a heat pump circuit 2; and a heater 33 for heating and a fan 34 arranged in a battery pack 30 of the electrically driven vehicle, the air conditioner supplying cooling/heating air into the cabin and the battery pack of the electrically-driven vehicle. In the battery pack, a selector valve is provided which alternately selects a first air circulation path passing through the heater 33 for heating, heat exchanger 32 for the battery, and a driving battery 31 in this order and a second air circulation path passing through the heater for heating and the heat exchanger for the battery in this order, and the fan is provided to circulate air to the first air circulation path and the second air circulation path.SELECTED DRAWING: Figure 1
