A flame retarder composition comprising, as indispensable components, four components consisting of two specified types of phosphate compounds; silicon dioxide or a metal oxide; and at least one member selected from among a higher aliphatic carboxylic acid, a metal salt of higher aliphatic carboxylic acid, a higher fatty acid amide compound and an ester from monohydric or polyhydric alcohol and higher aliphatic carboxylic acid. This flame retarder composition is free from secondary coagulation, and does not need incorporation of a halogenated flame retarder that when blended in a synthetic resin, releases harmful gas at combustion. The flame retarder composition enables imparting flame retardant properties to synthetic resins with the use of a small amount of flame retarder. (FIG. nil)
