Abstract

To provide a thermoplastic polyester resin composition which has a very good durability to alkaline solutions for a long period of time. That is, a thermoplastic polyester resin composition, wherein a thermoplastic polyester resin (A) is compounded with 1-25% by weight (in the total composition) of impact resistance rendering materials (B), 0.1-15% by weight (in the total composition) of a silicone compound and/or a fluorine compound (C), 1-50% by weight (in the total composition) of an inorganic filler (D), and 0.1-10% by weight of at least one polyfunctional compound (E) selected from the group consisting of an epoxy compound, an isocyanate compound and a carboxylic acid dianhydride. A molded article of the present invention has anti-stress properties even in a weld part thereof.
