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.
