PROBLEM TO BE SOLVED: To provide a film-shaped electromagnetic wave absorber which has fire retardancy and high wave absorbability, and its manufacture. SOLUTION: This is an electromagnetic wave absorber which has an electromagnetic absorbing wave layer 2 mainly composed of soft magnetic substance and high polymer coupling agents, and the high polymer coupling agent is 25,000 or over in average quantity of molecules, and also aromatic components within the molecule are 15 wt.% or more. The manufacture is as follows. An electromagnetic wave absorbing layer is made by applying and drying magnetic coating mainly composed of soft magnetic particles and high polymer coupling agents on a support 1.
