Abstract

An electronic apparatus is disclosed which is easily to suppress the error actions caused by the noise emitting from the circuit board or caused by the interference between the parts in the circuit board or the electromagnetic inductance between the signal wires. The constructure of the present invention is that the LSI2 is mounted on the circuit board 1, the wiring conductor 3 is disposed at the rear face of the circuit board under the LSI2. The electromagnetic interference suppresser A having the same size as the LSI2 is mounted between the LSI2 and the circuit board 1. Before the LSI2 is mounted, the electromagnetic interference suppresser A is fixed at either the LSI2 or the circuit board 1. The electromagnetic interference suppresser A is used to attenuate the unwanted radiating noise generated by LSI2, for weaken the inductance coupling between the LSI2 and the wiring conductor 3 so that the noise generated by the wiring conductor 3 is suppressed efficiently. The electromagnetic interference suppresser A comprises the conductive supporter and the insulative soft magnetic layer which provided at least on one face of the conductive supporter.
