PURPOSE:To produce a polycarbonate resin composition having excellent fluidity in molding, without lowering the properties of the base resin, by adding a small amount of a specific aluminum chelate compound to a polycarbonate resin. CONSTITUTION:100pts.wt. of a polycarbonate resin having a viscosity-average molecular weight of 15,000-35,000, preferably 20,000-30,000 is compounded with 0.001-0.1pt.wts., preferably 0.005-0.05pts.wt. of an aluminum chelate compound of formula (R<1> is OH, amino, 1-22C alkyl, 3-22C alkenyl, aryl, aralkyl, or alkylaryl; R<2> is R<1>, R<1>CO or R<1>O; 0<=m<=2; 1<=n<=3; m+n<=3) (e.g. diisopropoxyaluminum monooleyl Acetoacetate) and if necessary with an inorganic filler, a colorant, other additives or synthetic resins, and the mixture is melted and kneaded at 250-300 deg.C.
