Abstract (en)
An improved induction heating device for generating aerosol by heating an aerosol forming base substance is provided.An induction heating device 100 for heating an aerosol forming base substance 108, which comprises a susceptor 110 and an aerosol source 112, includes: an electric power source 102; a coil 106 for heating the susceptor 110 by induction heating; a parallel circuit 130 which includes a first circuit and a second circuit arranged in parallel in positions between the electric power source 102 and the coil 106, in which the first circuit is used for heating the susceptor 110, and the second circuit is used for obtaining a value relating to electric resistance or temperature of the susceptor 110; and an AC generation circuit 132 which is arranged in a position between the parallel circuit 130 and the coil 106 or between the parallel circuit 130 and the electric power source 102.
