摘要: The present invention relates to an electromagnetic shielding sheet capable of improving reliability. Particularly, the present invention provides a composite magnetic sheet for electromagnetic shielding structured such that an independent soft magnetic sheet, which has a low surface roughness, is laminated on the outermost surface of a soft magnetic sheet having a lamination structure, thereby implementing laminated composite sheets having different surface roughness or porosity characteristics; as a result, the reliability in an external hazardous environment, such as saline water, can be substantially enhanced while maintaining the efficiency of electromagnetic shielding.
