PROBLEM TO BE SOLVED: To provide a curtain with high antivirus property even under the radiation with visible light with low illuminance.SOLUTION: The curtain with high antivirus property includes at least one kind of particulates to be selected from tungstic oxide particulates and tungstic oxide composite material particulates. At least one kind of virus selected from low virulence avian influenza virus (H9N2), high virulence avian influenza virus (H5N1), and pig influenza virus is inoculated to a test piece to which the particulates are made to adhere in the range of 0.01 to 40 mg/cm, and then, the virus titer after radiating the visible light for 24 hours is evaluated. In this case, an inactivation effect R is not less than 1, R being expressed by formula: [R=logC-logA] (C is the virus titer TCIDafter the test piece without the adhesion processing is preserved under the visible light for 24 hours, and A is the virus titer TCIDafter the test piece with the particulates applied thereon is preserved under the visible light for 24 hours). |
