Abstract
An object of the present invention is to provide a liquid crystal polyester resin composition in which satisfactory fluidity and excellent mechanical properties as well as flame retardancy are obtained, and the generation of particles is suppressed, and a molded article composed of the liquid crystal polyester resin composition. The present invention relates to a liquid crystal polyester resin composition containing: 100 parts by mass of a liquid crystal polyester (A) including repeating units represented by the formulas (I) to (III), wherein Ar1 and Ar2 each represent one or more divalent aromatic groups, and p, q and r each represent a composition ratio (mol %) of each repeating unit in the liquid crystal polyester (A) and satisfy the following conditions, 35≤p≤90, 5≤q≤30, and 5≤r≤30; and 1 to 150 parts by mass of a fibrous titanium oxide (C).
