Abstract: A decontamination device configured to provide, on a short time scale, uniform decontamination of target articles without using expensive electron accelerators and to decontaminate such articles in large quantities. The device includes a device body composed of a decontamination region and an aeration region, a conveyance means for conveying an article, a mist supply means, a mist control means, and an aeration means. The mist supply means converts a decontamination agent into a corresponding mist and supplies the mist to the inside of the decontamination region. The mist control means includes vibration boards adjacent to internal wall surfaces of the decontamination region, and these boards are ultrasonically vibrated to generate sound flows from board surfaces by an ultrasound in the vertical direction. The mist inside the decontamination region is pressed by acoustic radiation to concentrate the mist on external surfaces of the article conveyed inside the decontamination region.
