| 发明名称 | Magnetic field shielding sheet for digitizer and method of manufacturing the same and portable terminal device using the same | ||
| 摘要 | A magnetic field shielding sheet includes: at least one layer thin magnetic sheet made of a Fe-based amorphous alloy and flake-treated so as to be separated into a plurality of fine pieces; a protective film that is adhered on one surface of the thin magnetic sheet via a first adhesive layer provided on one side of the protective film; and a double-sided tape that is adhered on the other surface of the thin magnetic sheet via a second adhesive layer provided on one side of the double-sided adhesive tape, wherein the thin magnetic sheet is obtained by heat treating an amorphous ribbon sheet made of the Fe-based amorphous alloy at a temperature of 300° C. to 480° C. A method of manufacturing the magnetic field shielding sheet, and a portable terminal device using the magnetic field shielding sheet are disclosed. | ||

| 主权项 | 1. A magnetic field shielding sheet for a digitizer, the magnetic field shielding sheet comprising: at least one layer thin magnetic sheet which is flake-treated so as to be separated into a plurality of fine pieces; a protective film that is adhered on one surface of the thin magnetic sheet via a first adhesive layer provided therebetween; and a double-sided adhesive tape that is adhered on the other surface of the thin magnetic sheet via a second adhesive layer provided therebetween, wherein the thin magnetic sheet is obtained by heat treating an amorphous ribbon sheet made of a Fe-based alloy at a temperature less than a crystallization temperature. | ||
