Molded article, method for manufacturing same, method for manufacturing fiber-reinforced plastic product, and method for improving antibacterial or antiviral properties

A method for manufacturing a molded article comprising:

• a step of applying inositol phosphate to at least a part of a surface of a molded article of a resin composition comprising a calcium compound and a resin;
• and
• a step of applying at least one metal ion selected from the group consisting of a silver ion, a zinc ion, and a copper ion to the surface to which the inositol phosphate is applied.

A method for manufacturing a fiber-reinforced plastic product comprising:

• a step of applying inositol phosphate to a surface of an outer layer of a fiber-reinforced plastic which comprises the outer layer comprising a calcium compound and a resin on at least a part of a surface thereof;
• and
• a step of applying at least one metal ion selected from the group consisting of a silver ion, a zinc ion, and a copper ion to the surface to which the inositol phosphate is applied.

A method for improving or imparting antibacterial or antiviral properties of a molded article comprising a calcium compound and a resin and having inositol phosphate on a surface thereof, the method comprising:

• a step of applying at least one metal ion selected from the group consisting of a silver ion, a zinc ion, and a copper ion to the surface having the inositol phosphate.
