Abstract: An object of the present invention is to provide an ultraviolet light irradiation sheet that can be decontaminated regardless of a shape of an object to be decontaminated. An ultraviolet light irradiation sheet (50) includes an optical fiber (20) which emits a part of propagating light from a side surface or an end surface; and a deformable sheet (10) which incorporates the optical fiber (20).

Since the ultraviolet light irradiation sheet does not diffuse bacteria and viruses by wind, the sterilization of the object to be sterilized can be performed without forming a closed space.
