摘要： Provided is an antiviral article that has a discoloration due to light being suppressed. An antiviral article comprising a cured product layer, wherein the cured product layer comprises a cured product of a curable resin composition, an antiviral agent obtained by supporting or containing a silver ion in a carrier, and a light stabilizer, and the cured product layer comprises, as the light stabilizer, one or more hindered amine-based compounds selected from the group consisting of an NH type hindered amine-based compound and an NR type hindered amine-based compound. The antiviral article preferably has the cured product layer on a base material.
