<P>PROBLEM TO BE SOLVED: To minimize exhibition of anisotropy in the radio wave absorption performance of a radio wave absorber produced by press molding. <P>SOLUTION: In the production method of a radio wave absorber, a molding material M containing thermoplastic resin beads with a radio wave absorbing material adhering to the surface thereof is set in a molding die 10 and press molded into a predetermined shape. When the press conditions are set in the operation, radio wave absorption characteristics of the radio wave absorber can be controlled. Since the thermoplastic resin beads with a radio wave absorbing material adhering to the surface thereof is used as the molding material, orientation in one direction of the radio wave absorbing material is regulated, and anisotropy can be minimized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
