Polyamide composition was obtained by adding addition agent in the polyamide chip. The addition agent was composed of phosphate and inorganic powder 0.01-3 wt%, higher fatty acid salt (C12-20) 0.03-2 wt%, and dispersing agent (I; n = 5-7) 1-3 wt% (for the total amount of addition agent). Thus, talc powder 120 g, calcium stearate 500 g, and dispersing agent 8.0 g were mixed with polyamide 6 (relative viscosity is 2.7) 100 kg and pelletized. The pellet was injection moulded at 235-250≦̸C (cylinder temp.) to make 60X150X10 (mm) plate.
