PROBLEM TO BE SOLVED: To provide a thermoforming electromagnetic wave absorption material that is easy to form and process, and has a high electromagnetic wave absorption capability after being formed even if it is a thin layer. SOLUTION: After having attached thermoplastic resin particles smaller than electromagnetic wave absorptive particles around the electromagnetic wave absorptive particles, heat treatment is done using a temperature higher than a glass-transition temperature of the thermoplastic resin. Further, as to this electromagnetic wave absorption material, the electromagnetic wave absorptive particles having gone through hydrophobic treatment are added to a thermoplastic resin manufacturing polymeric composite, which is suspension-polymerized in water liquid as suspension particles to accelerate the polymerization reaction.
