PURPOSE:To provide a heating device possible to conduct local heating and prevent the heat dispersion to the circumference at a minimum by exposing only the top part of a heat conductive member and enclosing other parts with a heat insulating material. CONSTITUTION:A heating device is used as the heating part 13 of an aromatic device constituted in such a manner that an aromatic is evaporated by heating an aromatic card 1 to obtain an aroma. The heating part 13 is formed by winding a nichrome wire 33 on a mica plate 32 formed into a stick, insulating the circumference with a glass wool 84, putting a copper plate 35 having a U-shaped section over this, and enclosing the base end part side with a heat insulating material 36 in the state where only the top part of the copper plate 35 is exposed. In this heating part 13, as the aromatic card 1 is heated by the exposed top part of the copper plate 35, the heating area can properly be limited and heated. |
