摘要： In foamable polystyrene resin particles that are obtained by granulating a polystyrene resin containing a flame retardant and a foaming agent, the flame retardant has a bromine atom in a molecule, contains less than 70% by mass of bromine, has a benzene ring in a molecule, and has a 5% by mass decomposition temperature in a range of from 200° C. to 300° C. the flame retardant is the sole source of bromine in the foamable polystyrene resin particles, a ratio (B:A) between (A) a by mass of the flame retardant contained in the total foamable polystyrene resin particles and (B) a % by mass of the flame retardant contained in the surface of the resin particles is in a range of from 0.8:1 to 1.2:1, and the amount of the flame retardant added is in a range of from 0.5% by mass to 5.0% by mass, based on 100 parts by mass of the resin fraction in the foamable polystyrene resin particles.
