To provide a noise suppression element which is efficiently coupled with a magnetic field to absorb and attenuate an induced current, for a nearby field and to provide an electromagnetic field absorbing and attenuating element which enhances an oblique incidence characteristic of a radio wave absorber, in particular, TM wave oblique incidence characteristic for a radiation wave from a distance.
A conductor line shaped in such a way as to induce a current, with respect to a direction of a predetermined alternating magnetic field, is formed on a substrate and a resistor 11 is disposed in an intermediate part of induced current induction areas 4, 5, 6, 7 due to the alternating magnetic field, thereby absorbing and attenuating an induced current. An induced current induction starting point and an induced current arrival ending point are wiring-connected and by constituting a closed circuit with respect to the induced current, this effect is much more enhanced. Thus, since the induced current is effectively absorbed and attenuated by the resistor when it flows in the closed circuit, an electromagnetic field being generated can be absorbed and attenuated. By combining this basic configuration, a nearby radiation magnetic field or distant radiation electromagnetic field that is also coupled with various alternating magnetic field components and being generated unexpectedly, can be absorbed and attenuated.
