Therefore, it has been apprehended that responsiveness of the temperature sensing unit to such a change of the ambient temperature is deteriorated.
  • the heated air blower for example, after moving the heated air blower concerned from a place where the ambient temperature is high to a place where the ambient temperature is low, it takes some time for the temperature sensing unit to detect a new ambient temperature. Hence, it has been apprehended that hot air at an optimum temperature cannot be supplied for such a while.

  • a heater wire 30 (a heating element) that drops a voltage to be applied through such a power supply cord C is provided in order to drive the motor 9b of the air blower unit 9. That is to say, in this embodiment, for the purpose of realizing weight reduction, downsizing and the like of the hair dryer 1, the motor 9b is used, in which a voltage to be actually inputted is lower than the voltage to be applied through the power supply cord C.

Meanwhile, to the heater unit H, 100% of the voltage is applied as it is.
  • a resistor such as the heater wire 30, which is accompanied with heat generation, is used as this heating element.
  • Use of the heater wire 30 as shown in this embodiment is suitable since an advantage is brought in terms of cost and the heater wire 30 can be arranged in the space of the housing 3 without occupying much of the space.
