Abstract
The present invention provides a liquid crystal polyester composition, comprising (i) 100 parts by weight of a liquid crystal polyester, and (ii) 65 to 100 parts by weight of a combination of a fibrous filler with a plate-like filler, wherein the fibrous filler has a number-average fiber diameter of 5 to 15 μm, and a number-average aspect ratio of 20 to 40, and a content ratio by weight of the fibrous filler to the plate-like filler is more than 1.0 and 1.6 or less; and a process for producing the liquid crystal polyester composition comprising a step of melt-kneading the above respective components with one another.
