PROBLEM TO BE SOLVED: To provide an electromagnetic wave suppression coating agent that is excellent in electromagnetic wave suppressiveness and insulation characteristics and can be applied without containing volatile organic solvent or water solvent.;SOLUTION: An electromagnetic wave suppression coating agent of the present application includes: a fluidity olefin-based elastomer including unsaturated bond; a cross-linking agent for bridging the elastomer; and ferrite powder. Because it has fluidity, it can be applied readily without containing volatile organic solvent or water solvent. Furthermore, it can have excellent electromagnetic wave suppressiveness and insulation characteristics by combination of the olefin-based elastomer and the ferrite powder.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
