Claim 0:
1. A misalignment detection device configured to detect misalignment of a second coil with respect to a first coil including a conductive wire wound around a coil axis of the first coil, comprising:
a first induction heating unit and a second induction heating unit which receive lines of magnetic force generated by the first coil and are juxtaposed line-symmetrically with a second axis, which intersects the coil axis and a first axis intersecting the coil axis, being a line of symmetry;
a first temperature measurement unit which is disposed adjacent to the first induction heating unit and outputs a first temperature;
a second temperature measurement unit which is disposed adjacent to the second induction heating unit and outputs a second temperature; and
a processing unit which detects misalignment of the second coil with respect to the first coil along the first axis on the basis of an evaluation value evaluating a difference between the first temperature and the second temperature,
wherein the first induction heating unit and the second induction heating unit are coils.
