Provided is a liquid crystal polyester resin composition comprising 100 parts by weight of a liquid crystal polyester resin, 2 to 50 parts by weight of hollow sphere having an average particle diameter of 5 to 500 mum and a volume hollowness of 60 to 80%, and 0 to 40 parts by weight of inorganic fiber, wherein said liquid crystal polyester resin composition has the specific range of fracture rate of the hollow sphere. The liquid crystal polyester resing composition gives a molded product having necessary mechanical physical properties, light-weighted and excellently low thermal conductivity, with good reproducibility.
