Disclosed is an inductive heating device in which the under-surface of a ferrite element (6) arranged below a heating coil (4) in the perpendicular direction and the under-surface of a coil base (5) are formed in the same plane and are directly placed on a heat-radiating plate (12A). Variations in the thickness of the ferrite element (6) are absorbed by filling at least some of the space between the ferrite element (6) and an insulating member (9) that is gripped between the heating coil (4) and the ferrite element (6), with a heat-conducting member (8), and a state is therefore produced in which thermal linkage from the heating coil (4) to the heat-radiating plate (12A) is achieved. L'invention concerne un dispositif de chauffage par induction comprenant un élément en ferrite (6) placé perpendiculairement sous un serpentin de chauffage (4) et un socle (5) de serpentin, la surface de dessous de l'élément en ferrite (5) et la surface de dessous du socle (5) de serpentin occupant un même plan et étant mis au contact direct d'une plaque de rayonnement thermique (12A). Les variations d'épaisseur de l'élément en ferrite (6) sont absorbées par un matériau thermoconducteur (8) remplissant au moins partiellement l'espace séparant l'élément en ferrite (6) d'un corps isolant (9) pris en sandwich entre le serpentin de chauffage (4) et l'élément en ferrite (6), de manière à obtenir une liaison thermique entre le serpentin de chauffage (4) et la plaque de rayonnement thermique (12A).
