PROBLEM TO BE SOLVED: To provide an air conditioner capable of improving reliability of an equipment by preventing excessive rise in refrigerant temperature even if refrigerant is heated using an electromagnetic induction heating method. SOLUTION: The air conditioner 1 uses a refrigeration cycle having a compressor 21, and refrigerant tubing F covered by a magnetic tube F2 around the periphery, and is provided with a coil 68, an electromagnetic induction thermistor 14, and a control part 11. The coil 68 generates a magnetic field for inductively heating the magnetic tube F2. The electromagnetic induction thermistor 14 detects the temperature of the refrigerant that flows in an accumulator tube F. The control part 11 allows the generation of a magnetic field at a level higher than a first magnetic field level when a magnetic field level increase condition is met. The magnetic field level increase condition is when there is a change in the temperature detected by the electromagnetic induction thermistor 14 before and after the magnetic field generated by the coil 68 is raised to the first electromagnetic field level.
