The present invention provides a resin composition containing a liquid crystalline polyester and a high dielectric material filler. The present invention also provides a molded article of the liquid crystalline polyester resin composition. The liquid crystalline polyester resin composition of the present invention comprises 50 to 80% by volume of a liquid crystalline polyester which has 40% by mol or more of a 2,6-naphthalenediyl group as an aromatic group, also has a flow initiation temperature of 280° C. or higher, and shows a melt tension of 1 g or more measured at a temperature higher than flow initiation temperature; and 20 to 50% by volume of a high dielectric material filler. The liquid crystalline polyester resin composition can be formed into composition pellets easily and stably by a strand method, and a molded article obtained from the liquid crystalline polyester resin composition is excellent in flexural strength and dielectric characteristics.
