To obtain a composite magnetic body and an electromagnetic interference suppresser effective for suppressing electromagnetic interference in high-frequency electronic apparatuses such as movable communication apparatuses.
A composite magnetic body is substantially composed of soft magnetic alloy powder and binder, wherein the Curie temperature Tc of the soft magnetic alloy powder is nearly equal to that of bulk alloy material which serves as the starting material of the alloy powder and is so prescribed in composition as to make its crystal anisotropic constant nearly equal to zero. The Curie temperature Tc of the soft magnetic alloy powder is nearly equal to that of bulk allay material which serves as the starting material of the alloy powder and is so prescribed in composition as to make its magnetostriction constant nearly equal to zero. It is preferable that the non-oxide of the soft magnetic alloy powder is controlled in composition taking a measurement of a Curie temperature.
