Abstract: The invention discloses a heating device for an electric hair dryer, said heating device comprising heating wires (2) and mica sheets (1); said heating wires (2) are folded to be corrugation, such that the distance between peaks is 5.0 mm or more; and said heating wires (2) are zigzag wound on the mica sheets (1) in stepped, laminated and beveled arrangements. The heating device for the electric hair dryer of the present invention, by deepening corrugation and employing zigzag arrangement, increases the clearance between heating wires, areas of heat dispersion and windward surface, shortens the structure of the heating device to save the cost, improves the heat dispersion of the heating device, and addresses a series of problems, such as less power of the electric hair dryer, larger bulk, higher air temperature, less air volume, turning red of heating wires, the contact of the wires, so as to provide an electric hair dryer having advantages of refinement and strong heat dispersion.
