Abstract

A hair dryer includes a heater, a fan, a motor for driving the fan, a body case that accommodates the heater, the fan, and the motor, and a thermal barrier tube disposed between the body case and the heater. The diameter of the fan is allowed to be 90 mm or more, and an air quantity formed by the fan is allowed to be 1.0 m 3 to 1.4 m 3 /min, thereby enabling reduction of noise while resulting in the sufficient air quantity.
