PROBLEM TO BE SOLVED: To provide a flame retardant agent capable of providing a flame-retardant polyester-based fiber in which a color difference from a polyester-based fiber to which only a dyeing process is applied is sufficiently small even when a flame-retardant processing is applied to a polyester-based fiber while a dyeing process is applied.SOLUTION: The flame retardant agent for a polyester-based fiber contains a phosphorus compound and an anionic surfactant that is represented by the general formula (1) in which m and n are m:n=1:0.2-1:2.0 and has 2-30 of an average polymerization degree (N) of phenolic skeletons. The content of the anionic surfactant is 5-40 pts.mass with respect to 100 pts.mass of the phosphorus compound.
