1. An aerosol-generating apparatus for inductively heating a susceptor of an aerosol-forming body that includes the susceptor and an aerosol source, the aerosol-generating apparatus comprising:
a housing into which the aerosol-forming body can be inserted,
wherein the housing comprises
a power supply;
an alternating current generation circuit for generating an alternating current from a power supplied from the power supply;
an inductive heating circuit for inductively heating the susceptor;
a controller configured to:
detect a voltage and a current of a circuit including the inductive heating circuit to which the alternating current generated by the alternating current generation circuit is supplied, and
start the inductive heating in a case in which, based on an impedance obtained from the detected voltage and current, it is determined that the susceptor is in the housing of the aerosol-generating apparatus; and
a voltage adjustment circuit connected to the power supply and the controller,
wherein a current to be detected by the controller is detected on a path between the power supply and the alternative current generation circuit at a position to which the alternative current generation circuit is closer than a branch point on the path to the voltage adjustment circuit.
