Abstract: Disclosed is a flame retardant composition having excellent flame retardancy and processability, providing a flame-retardant synthetic resin composition including this flame retardant composition and having excellent flame retardancy and processability. Specifically, the following components are used in combination: as component (A), 20 to 50 parts by mass of at least one type of melamine salt selected from the group consisting of melamine orthophosphate, melamine pyrophosphate, and melamine polyphosphate; as component (B), 50 to 80 parts by mass of at least one type of piperazine salt selected from the group consisting of piperazine orthophosphate, piperazine pyrophosphate, and piperazine polyphosphate (the total of component (A) and component (B) is 100 parts by mass); and as component (C), 0.01 to 20.0 parts by mass of a bicyclophosphoric ester compound represented by the following general formula (1). The details of formula (1) are as described in the Description.
