    Abstract: A polyarylene sulfide (PAS) resin composition that contains a PAS resin and an antiviral agent, has superior antibacterial and antiviral properties, and maintains its intrinsic mechanical strength, weld strength in particular, an article molded from this resin composition, and methods for producing them are provided. More specifically, the PAS resin composition is one that contains the PAS resin and antivirus agent as its essential components, the molded article is one molded from it, and the production methods, for the PAS resin composition and the molded article, are one that includes a step of melt-kneading the PAS resin and antiviral agent in a temperature range of equal to or higher than the melting point of the PAS resin and one in which the PAS resin composition is melted and molded. The antiviral agent is metal ion-containing phosphate and/or borate glass.
