PROBLEM TO BE SOLVED: To obtain a liquid crystal polymer composition reduced in the tendency to form burrs when molded and improved in the environmental stability of a laser focal point, dimensional accuracy, and vibration-damping properties by including a liquid crystal polymer with a particulate filler and a fibrous filler in a specified ratio. SOLUTION: This composition comprises 100 pts.wt. liquid crystal polymer having a relative viscosity of at least 2.0 dl/g, desirably, 2.0-10.0 dl/g as measured in a 0.1 wt.% solution in pentafluorophenol at 60 deg.C, 5-100 pts.wt., desirably, 10-80 pts.wt. at least one particulate filler selected from among talc, titanium oxide, glass beads, and silica and having a mean particle diameter of 0.1-50μm and an average aspect ratio of 1-2, and 5-100 pts.wt., desirably, 10-80 pts.wt. at least one fibrous filler selected from a milled fiber and wollastonite and having an average fiber diameter of 0.5-20μm and an average aspect ratio of at most 10. The total content of the fillers is at most 150 pts.wt., desirably, at most 110 pts.wt.
