<p>Disclosed is a compressed powder core that makes it possible to improve the coating layer that covers a core body, control loss of magnetic characteristics, and improve core strength. A coating layer (3) made from a methacrylic acid diester is formed by impregnating the entire surface of a core body (2), made by solidifying and molding an amorphous soft magnetic alloy powder by means of a binder. Thus, core strength can be effectively improved compared with the past, while controlling loss of magnetic characteristics.</p> |
