Zusammenfassung:	PURPOSE:To obtain the titled product of markedly improved surface smoothness capable of giving high adhesivity and metallic gloss, by incorporating silicone oil in a polyamide resin composition reinforced with wollastonite of specific particle size. CONSTITUTION:Homogeneous incorporation of (A) 100pts.wt. of a polyamide resin composition reinforced with 25-50 (pref. 30-45) wt% of wollastonite of an average particle size 0.05-20 (pref. 3-15) mu with (B) 0.03-5 (pref. 0.1-3) pts.wt. of silicone oil pref. polysiloxane of formula (m is 1-4, n is 1-5) is performed followed by kneading in a molten state then molding in an appropriate process to obtain the objective product. Alternatively, said wollastonite and silicone oil are intimately mixed beforehand, followed by homogeneous incorporation of said polyamide resin in the form of pellets, powder, or chips, then kneading in a molten state using extruder to effect pelletization. The resulting pellets are melted followed by molding in an appropriate process to obtain the objective product.
