Abstract: A thin, light and soft electromagnetic wave absorber is disclosed exhibiting an excellent workability. The first conductor element group of a first conductor element layer consists of aligned cross conductor elements and square conductor elements in regions surrounded by cross conductor elements. A radio wave incident from the first conductor element layer side is received by each element, internally subjected to multiple reflection and then absorbed by a first loss material layer. Since the first conductor element group is realized by the cross conductor elements and the square conductor elements, receiving effect is enhanced and the radio wave can be collected with a high collection efficiency.

Abstract: An electromagnetic interference suppressor of substantially unpressurized sheet form is obtained by applying and drying a magnetic paint, and comprises 30 to 80% by volume of soft magnetic powder and 20 to 70% by volume of a binder. The binder is an elastomer or a resin that a glass transition point and/or a softening point is 50° C. or more and a storage modulus (E?) is 107 Pa (JIS K 7244-1) or more in a state containing neither solvent nor filler at room temperature. This electromagnetic interference suppressor exerts a superior electromagnetic interference suppressing effect.

Abstract: A conductive pattern basically has a substantially polygonal outline shape which is a polygon and can have a high peak value of the electromagnetic wave absorption amount as compared to a case when the conductive pattern has a circular outline shape. Thus, the conductive pattern is basically a polygon and at least one corner portion is shaped in curve. This reduces or even minimizes the shift of the frequency at which the absorption amount becomes a peak value by the polarization direction of the electromagnetic wave. Accordingly, in at least one embodiment, it is possible to realize an electromagnetic absorber having an excellent electromagnetic wave absorption characteristic exhibiting a high peak value of the absorption amount of the electromagnetic wave and a small shift of frequency at which the absorption amount becomes a peak value by the polarization direction of the electromagnetic wave.
