摘要： An induction heater for a device for heating tobacco or aromatic herbs, in particular of the heat-not-burn type. The induction heater includes at least one inductor having at least one electrically insulating layer and at least one electrically conductive track fixed to the at least one electrically insulating layer. The at least one inductor is adapted to be arranged about a metal tube in which part of a cigarette can be inserted, and the metal tube is adapted to be heated by induction by the at least one inductor.
