Abstract
A composite magnetic article for use as an electromagnetic interference suppressing body, which comprises soft magnetic powder of at least one soft magnetic composition having a magnetostriction constant, each of particles of the powder being flaky, and organic binding agent binding said soft magnetic powder dispersed therein. The soft magnetic powder is as annealed after being worked flaky. The flaky particles of the soft magnetic powder have an average thickness less than a skin depth within which the skin effect occurs at a frequency band for which said composite magnetic article is used, each having an oxide outer layers.
