(57) Abstract: Provided is a decontamination device whereby, by employing a mist circulation dispersion mechanism, a 
perfect decontamination result can be achieved by supplying the proper amount of a decontamination agent to a room to 
be decontaminated, and the working time for aeration, etc., can be shortened and a decontamination operation can be made 
efficient. The present invention is provided with a mist supply means and a mist circulation dispersion mechanism, the mist 
supply means converting a decontamination chemical to a decontamination mist and supplying the decontamination mist 
to the inside of a working room. The mist circulation dispersion mechanism is provided with a vibration panel disposed in 
e the vicinity of an inside wall surface of the working room, and the vibration panel is caused to ultrasonically oscillate, and

an acoustic flow due to ultrasonic waves is generated in the perpendicular direction from the panel surface. Pressure due to 
acoustic radiation pressure is applied to the decontamination mist supplied into the working room, and the decontamination 
mis is thereby circulated and dispersed in the working room.
