Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a flame retardant resin composition capable of obtaining a molded article having small warps on molding, and having a high mechanical strength and heat resistance, and an optical drive structure component by using the same. SOLUTION: This flame retardant resin composition includes (A) 100 pts.mass resin component containing 60 to 90 mass% polycarbonate resin and 40 to 10 mass% polyester resin, (B) 5 to 15 pts.mass phosphoric ester of formula (I) [wherein, X is a divalent aromatic group; and R1to R4are each substituted or non-substituted phenyl] based on 100 pts.mass component (A), (C) 0.01 to 0.5 pt.mass another organic phosphoric ester based on 100 pts.mass component (A) and 15 to 60 pts.mass of the total of (D-1) glass fiber and (D-2) a scale-like inorganic filler based on 100 pts.mass component (A), wherein (D-1)/(D-2)=0.2 to 1.5.
