Abstract
A flame retardant with which fire retardancy is improved and the fire retardancy is able to be secured stably for a long time is provided. An internal layercontaining a polymer and a flame retardant factor layerthat is formed outside of the internal layerand that contains a polymer to which at least one of a sulfonate group and a sulfonate base is bonded are included. Thereby, compared to a case that the flame retardant factor layeris not included, moisture is hardly absorbed, and respective particles of the flame retardant are inhibited from being adhered to each other. Accordingly, blocking is inhibited.
