The present disclosure relates to a magnetic shielding tape, which is capable of shielding a high-to-low frequency of a signal transmitted through a cable in shielding of a magnetic field which flows in such a cable or is emitted therefrom, and a method for manufacturing the same. The basic magnetic shielding tape comprises: —a thin film magnetic layer including at least one metal ribbon sheet which is divided into a plurality of fine pieces by flaking process, and a gap provided between adjacent fine pieces among the plurality of fine pieces; —a cover film layer adhered to one side surface of the thin film magnetic layer through a first adhesive layer; and—a conductive layer adhered to the other side surface of the thin film magnetic layer through a second adhesive layer, wherein a size of the gap is determined according to a frequency band of the signal.
