PRODUCTION METHOD FOR ELECTROMAGNETIC WAVE ABSORBER

PROBLEM TO BE SOLVED: To obtain a production method for electromagnetic wave absorber capable of carrying out an effective mass production of intermediate particles and inhibiting adhesion of the particles to each other. SOLUTION: This electromagnetic wave absorbing heating element 10 is obtained by coating a core material 12 with a coating solution dispersed with the electromagnetic wave absorbing heating material 18 in a coating solution and then curing. A mass of intermediate particles are effectively produced by coating the core material with the coating solution by agitating a mass of core materials 12 with the coating solution. Adhesion of each intermediate particle is inhibited by forming a film on the surface of the intermediate particle through adhesion of a film forming solvent to the intermediate particle before curing the solution mixture of the mass intermediate particles. This method is capable of effectively producing a mass of electromagnetic wave absorbing heating elements 10 because the method can effectively produce a mass of intermediate particles and inhibit adhesion of each intermediate particle.
