Abstract:
1. A reusable part-housing container, which is made of an electrically conductive polypropylene resin composition comprising: (1) a % by weight (a>0) of a propylene polymer which has a portion having not less than 95% by weight of crystallinity that occupies not less than 60% by weight of the propylene polymer, and which contains not more than 20% by weight of ethylene; (2) b % by weight (b>0) of a propylene random copolymer containing 1 to 7% by weight of ethylene which has a tensile elongation (23° C.) of not less than 100%; (3) c % by weight (c>0) of an electrically conductive filler, wherein the following relationships are satisfied: said resin composition having a melt flow rate of 10 to 80 g/10 min; said container comprising: a recessed section for housing and supporting a part; and a shutter section for preventing the part from being out of the recessed section, the shutter section being placed at an opening of the recessed section in a manner so as to be opened and closed.
