Disclosed is an air conditioner which can suppress excessive heating in a member heated via induction heating. The air conditioner (1) has a compressor (21), an exterior heat exchanger (23), an electric expansion valve (24), and an interior heat exchanger (41), and is provided with a coil (68) and a controller (11). The coil (68) generates a magnetic field for inductively heating an accumulator tube (F). The controller (11) ascertains the quantity of circulating coolant in a refrigeration cycle which includes the compressor (21), the interior heat exchanger (41), the electric expansion valve (24), and the exterior heat exchanger (23), and causes the coil (68) to generate a magnetic field when the quantity of circulating coolant increases.
