The present invention provides a fog generating device. Through generating warm fog lingering around the skin surface, skin care effects can be enhanced. The fog generating device is provided with an ultrasonic fog generating device (2) for enabling an ultrasonic vibrator (7) inside generating liquid to work to generate ultrasonic wave (M1) a heating fog generating device (3) for heating the generating liquid to generate heating fog (M2) and a mixed area (A1) for generating mixed fog (M3) formed by mixing the ultrasonic wave (M1) with the heating fog (M2) in the mixed area (A1).
