PROBLEM TO BE SOLVED: To provide a flame-retardant material which contains a polymer prepared by polymerizing monomers containing an acrylic ester, as a base material, having flame retardancy satisfying the requirements of V-0 of UL-94, and further contains other fillers such as a magnetic filler. SOLUTION: The flame-retardant material having≤15 vol.% of a compounded proportion of aluminum hydroxide, and 2-3 vol.% of a compounded proportion of an intumescent-type flame retardant regulated so that the ratio (vol.%) of the compounded proportions of the intumescent-type flame retardant to the aluminum hydroxide by volume may be (1:3) to (1:6) satisfies the requirements of the V-0 of the UL-94, and the compound obtained by adding about 50 vol.% of ferrite thereto can satisfactorily secure electromagnetic wave absorption properties.
