Patent ID: 8617437

Claim:
A flame retardant that has a flame retardant (a) component, comprising 50 to 97% by mass of a metal hydrate (a-1) component and 3 to 50% by mass of a filler (a-2) component, where the total of the metal hydrate (a-1) component and the filler (a-2) component is 100% by mass, wherein the filler (a-2) component is a zeolite represented by a general formula: xM 2/n O.Al 2 O 3 .ySiO 2 .zH 2 O, where M represents one or more metal elements selected from a group consisting of K, Na, Mg, Ca, Fe and Zn, n represents a valence of the metal element, and x, y and z represent arbitrary positive values; and wherein a moisture content of the filler (a-2) component is 10% by mass or more.
