    • A hair straightener heating element comprises: a base, a working plate, a heating sheet, a thermal insulation sheet, and a silica gel pad. The base is provided with an accommodation groove thereon. The silica gel pad is arranged in the accommodation groove. The thermal insulation sheet is fitted into the silica gel pad. The heating sheet is arranged on the thermal insulation sheet. The working plate has an inverted “U” shape, and cooperates with the base to sandwich the heating sheet, the thermal insulation sheet and the silica gel pad between the working plate and the base. The heating sheet is attached and matches a bottom surface of the working plate. The heating element separates a frame and a working plate into two devices, and provides a good contact between a heating sheet and the working plate so as to be isolated from the frame. The heating sheet immediately conducts heat to the working plate, and rapidly raises the temperature of the working plate, thereby enhancing a heating rate.
