PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber that has good characteristics in electromagnetic wave absorption and flammability. SOLUTION: This electromagnetic wave absorber contains an organic bond agent, a carbon powder having a specific surface of 20 to 110 m<SP>2</SP>/g and a flame retardant. In this absorber, the flame retardant is a hydroxide or a phosphorescence, the carbon powder is a boron solid carbon black having an electric resistivity of 0.1Ωcm or less in JIS K 1469, or the hydroxide is an aluminum hydroxide or the phosphide is a red phosphorus.
