PURPOSE:To improved electric wave absorbing characteristics as well as machining property, forming property, and execution property of an electric wave absorber utilizing ferrite. CONSTITUTION:In the title absorber, a magnetic layer 2 is provided on a metal layer 1 and further a dielectric layer 3 is laminated on it in one piece. The magnetic layer 2 allows a needle-shaped ferrite sintered body with a diameter of 1-10mm and an aspect ratio of 5 or higher to be aligned so that the direction of the needle shape is in vertical direction for the plate surface of the layer and these to be combined by resin. The magnetic layer 2 obtains characteristics where the real part of permeability is large at a wider frequency range. |
