An electromagnetic wave-absorbing composition is obtained by dispersing in a base polymer a magnetic powder coated with electrically insulating inorganic fines and optionally, a heat conductive powder. The composition has a high breakdown voltage, and can be applied to any adequate site within electronic equipment without a need to pay substantial attention to short-circuits.
