To provide a vehicular air conditioner which improves the air-conditioning efficiency.SOLUTION: A vehicular air conditioner 10 includes an air-conditioning circuit 20, a HVAC 80 which has a drain port 83 for discharging condensed water produced on an air cooling part 22 and a drainage unit 90 which discharges the condensed water to an external part. The drainage unit 90 at least includes a heat exchange course 91 having a heat exchange part 91a provided on such a position as to cause condensed water to perform heat exchange with an air heating part 21 upon a cooling operation, a discharge course 92 which discharges condensed water to an external part without passing through the heat exchange part 91a and a valve part 93 which can switch a connection destination of the drain port 83 to the heat exchange course 91 or the discharge course 92.SELECTED DRAWING: Figure 1
