Abstract
A shielding sticker for use on a cellular phone against electromagnetic waves generated by the phone and having negative influence on a person using such a phone is made up of a conductive shielding screen and a conductive ring. The conductive shielding screen is woven by fiber reeled from a mixed material composed of carbon, lead and sodium. The conductive ring is made of a metal or non-mental material. The conductive shielding screen is adhered to the conductive ring by a conductive adhesive to produce an integral sticker shielding against electromagnetic waves produced by a cellular phone in operation.
