Abstract
Provided is a magnetic field shield sheet for a digitizer, which blocks an effect of a magnetic field generated from various components of a main body of the portable terminal device and at the same time improves the sensitivity of an electronic pen when a digitizer feature is implemented in the portable terminal device, while minimizing an influence upon a geomagnetic sensor. The magnetic field shield sheet includes: at least one layer thin magnetic sheet made of a nanocrystalline 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.
