Abstract

Disclosed are a mobile phone protective case and a magnetism isolation sheet thereof. The magnetism isolation sheet comprises a middle magnetically permeable layer (200) made of a material having a magnetic permeability and having a printing property, and further comprises a protective layer group. The magnetism isolation sheet strengthens the strength of the middle magnetically permeable layer (200) by arranging the protective layer group on two faces or any face in the vertical direction of the middle magnetically permeable layer (200) in a stacked manner, thereby ensuring the strength of the magnetism isolation sheet and ensuring that the magnetism isolation sheet does not break easily in use. For this reason, correspondingly, a mobile phone protective case provided with the magnetism isolation sheet is easy to maintain, and the service life thereof is relatively long. In addition, since the middle magnetically permeable layer (200) and/or the protective layer group both have a printing property, different patterns of various colours can be printed, according to actual demands, on the middle magnetically permeable layer (200) and/or the protective layer group so as to improve the appearance of the magnetism isolation sheet and facilitate promotion.
