A flame-retardant resin composition which comprises a base resin and a flame retardant comprising (A) a calcium hydrogen phosphate and (B) at least one ingredient selected among (B1) a phosphorus compound, (B2) a nitrogen compound, (B3) a boron compound (such as a metal borate), (B4) a silicon compound (such as a (poly)organosiloxane or zeolite), and (B5) a metal compound (such as a metal hydroxide or metal oxide). The calcium hydrogen phosphate (A) may be, for example, a substantially anhydrous one. The phosphorus compound (B1) may be a (poly)phosphoric acid salt, a condensate of an organophosphorus compound, red phosphorus, etc. The nitrogen compound (B2) may be a salt of an aminated cyclic nitrogen compound with an oxyacid, a salt of an aminated cyclic nitrogen compound with a hydroxylated nitrogen compound, a urea compound, etc. The resin composition can have flame retardancy without the need of containing a halogenated flame retardant.
