摘要
Provided are a roll-shaped magnetic field shielding sheet, a method of manufacturing a magnetic field shielding sheet, and an antenna module using the same, which can improve the efficiency of the overall production process by improving a heat treatment process for a thin film magnetic sheet. The magnetic field shielding sheet includes: at least one thin film magnetic sheet; an insulating layer or insulating layers formed on one or either side of the at least one thin film magnetic sheet; and an adhesive layer formed between the insulating layers of the adjacent thin film magnetic sheets to laminate and bond the thin film magnetic sheets, wherein the thin film magnetic sheet is flake-treated to be divided into a plurality of magnetic substance fragments.
