Patent ID: 8030379

Claim:
A polycarbonate resin composition comprising 4 to 50 parts by mass of a nonmetallic inorganic filler (B) and 0.01 to 1 part by mass of a compound (C) relative to 100 parts by mass of a resin mixture (A) of 60 to 97% by mass of an aromatic polycarbonate resin (a-1) and 40 to 3% by mass of a fatty acid polyester (a-2), wherein the aromatic polycarbonate resin (a-1) is a polycarbonate-polyorganosiloxane copolymer comprising a polycarbonate section having a structural unit represented by general formula (5) and a polyorganosiloxane section having a structural unit represented by general formula (6): wherein R 5 and R 6 each represent a C 1 -C 6 alkyl group or a phenyl group and are identical or different, R 7 to R 10 each represent a C 1 -C 6 alkyl group or a phenyl group and are identical or different, R 11 represents a divalent organic residual group comprising an aliphatic or aromatic group, Z represents a single bond, a C 1 -C 20 alkylene group or a C 2 -C 20 alkylidene group, a C 5 -C 20 cycloalkylene group or a C 5 -C 20 cycloalkylidene group or a SO 2 , SO, S, O, or CO bond, e and f each are an integer of 0 to 4, and n is an integer of 1 to 150, and having a terminal group represented by general formula (4): wherein R 4 represents a C 1 -C 35 alkyl group and d represents an integer of 0 to 5, wherein the resin mixture (A) has the polyorganosiloxane in an amount of 0.1 to 3.2% by mass; the nonmetallic inorganic filler (B) is a glass fiber, wherein the glass fiber diameter is 3 to 30 μm and the glass fiber length is 1 to 6 mm, and the glass fiber length after kneading in the polycarbonate resin composition is 0.01 to 2 mm; the compound (C) is at least one of a phosphite ester and a phosphate ester; and the fatty acid polyester (a-2) is a polylactic acid.
