PROBLEM TO BE SOLVED: To obtain an injection molded article having low shrinkage anisotropy in molding and resistant to fibrillation by using a liquid crystalline resin. SOLUTION: Neuburg siliceous earth is filled as a filler for the liquid crystalline resin. The particle diameter of the Neuburg siliceous earth is e.g. 0.1-90μm and the filling amount is e.g. 0.1-150 pts.mass based on 100 pts.mass of the liquid crystalline resin. The composition may be filled further with glass fibers and other inorganic fillers in an amount of 0.1-150 pts.mass each. Filling of Neuburg siliceous earth reduces orientation of molecular chains in the case of flowing the liquid crystalline resin in a cavity of a mold and, accordingly, reduces shrinkage anisotropy in molding and suppresses fibrillation.
