PROBLEM TO BE SOLVED: To provide an automotive part which is produced from a polylactic acid-based resin composition and is excellent in heat resistance and flexural strength. SOLUTION: This automotive part is characterized by being produced from a polylactic acid-based resin composition comprising 20 to 60 pts.wt. of (A) a polylactic acid-based resin, 40 to 80 pts.wt. of (B) a propylenic resin composition comprising the following (b1) to (b4) [the total amount of (A) and (B) is 100 pts.wt.], 51 to 100 pts.wt. of (C) glass fibers, and 0.1 to 20 pts.wt. of (D) a modified propylenic resin. (b1) 83 to 58 wt.% of a specific crystalline propylene block copolymer, (b2) 0.5 to 7 wt.% of a specific propylenic homopolymer, (b3) 1 to 10 wt.% of a specific ethylene-1-butene random copolymer, and (b4) 15 to 25 wt.% of talc having a specific average particle diameter, [the total amount of (b1) to (b4) is 100 wt.%].
