The present invention is a flame-retardant thermoplastic resin composition characterized by combining (A) (poly) phosphate compound represented by the following general formula (1), (B) (poly) phosphate compound represented by the following general formula (3) and (C) polycarbodiimide described in claim 1. n in the formula (1) is a number of 1˜100, X1 is a triazine derivative represented by the following general formula (2) and P is a number satisfying a relational formula 0<p≦̸n+2. Z1 and Z2 in the formula (2) are groups selected from a —NR5R6 group [herein, R5 and R6 are a hydrogen atom, an alkyl group having 1˜6 carbon atoms or a methylol group], a hydroxyl group, a mercapto group, an alkyl group having 1˜10 carbon atoms, an alkoxy group having 1˜10 carbon atoms, a phenyl group or a vinyl group. r in the general formula (3) is a number of 1˜100, Y1 is a diamine containing [R1R2N(CH2)mNR3R4], piperazine or a diamine containing a piperazine ring. R1, R2, R3 and R4 are each a hydrogen atom, or an alkyl group having 1˜5 carbon atoms, m is an integer of 1˜10, q is a number satisfying a relational formula 0<q≦̸r+2.
