Ultraviolet light irradiation sheet

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). The ultraviolet light irradiation sheet uniformly or partially irradiates ultraviolet light from a sheet surface. Therefore, by covering the object to be sterilized with the ultraviolet light irradiation sheet, a material having a complicated shape or an amorphous shape can be irradiated with the ultraviolet light without making a shade. 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.
