PROBLEM TO BE SOLVED: To obtain a polylefin resin composition which shows excellent flame retardancy even when it contains only a small amount of a flame retardant by mixing a polyolefin resin with a polyammonium phosphate compound, a novel phosphate, a nitrogenous compound, etc. SOLUTION: This composition is prepared by mixing a polyolefin resin with 1-30wt.% polyammonium posphayte compound (A) with 0.1-30wt.% (condensed) amine phosphate (B) represented by formula I [wherein n is 1-100; X1 is R1 R2 N (CH2 )n NR3 R4 , piperazine, a diamine containing a piperazine ring; R1 to R4 are each H or a 1-5C alkyl; m is 1-10; Y1 is NH3 or a triazine derivative represented by formula II; Z1 and Z2 are each -NR5 R6 , hydroxyl, mercapto, a 1-10C alkyl, a 1-10C alkoxyl, a phenyl or vinyl; and R5 and R6 are each a 1-6C alkyl or methylol], 0.1-30wt.% nitrogenous compound (C) and 0.1-20wt.% polyhydric alcohol (D). The total amount of components A, B, C and/or D should be 10-50wt.% based on the entire composition.
