PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber for milli-wave which can exhibit high and stable absorption characteristics in an object milli-wave band, even if the absorber is subjected to a thermal change or bonding. SOLUTION: Each of electromagnetic wave absorbers 1 and 1a contains a heat-resistant sheet 2 made of a rubber or plastic material, soft magnetic metal powder 4 embedded in the matrix of the rubber or plastic material, aluminum foil (metal layer) 6 or a plated-Cu layer (metal layer) 8, and a plated-Ni layer (metal layer) 9 formed on either one surface of the sheet 2 to cover the surface. |
