Beschreibung
Zusammenfassung:	The present invention relates to a polyester resin composition and a molded article thereof, the polyester resin composition being obtained by blending at least (A) 100 parts by mass of a polybutyleneterephthalate resin, (B) 15-100 parts by mass of an amorphous resin, and (C) 0.010-5.0 parts by mass of an epoxy resin having a special structure, and the melting point of the polyester resin composition being 210-221 DEG C inclusive. The polyester resin composition and the molded product thereof have excellent laser transmittance, and can be used for various automobile electrical installation parts (various control units, various sensors and the like), connectors, switch parts, relay parts and the like. 本发明涉及一种聚酯树脂组合物及其成型品，它由至少(A)聚对苯二甲酸丁二酯树脂100质量份，(B)非晶树脂15-100质量份以及(C)特殊结构环氧树脂0.010-5.0质量份配合而得到、并且该聚酯树脂组合物的熔点在210℃以上，221℃以下。本发明该聚酯树脂组合物及其成型品具有优异的激光透过率，可用于各种汽车用电气安装部件(各种控制单元、各种传感器等)、连接器类、开关部件、继电器部件等。
