To obtain a molded product consisting of a non-halogenated thermoplastic resin composition having antimicrobial activity and high rigidity without emitting any acidic gas even after its incineration or damaging any incinerator due to high combustion calory and producing little incineration residues.

This composition is such one as to consist of a non-halogenated thermoplastic resin and bamboo powder. The other objective molded product having antimicrobial activity is characterized by being obtained through subjecting the composition including 20-80 wt.% of the bamboo powder to thermoforming, such as injection molding, extrusion, calendering, vacuum forming, pressure forming or press molding of sheets, and is useful in the fields of light electrical parts, automobile parts, building materials and kitchen utensiles.
