The functional module 30 is placed between the two layers of artificial fiber fabric during the processing, and the functional module 30 is not fixed at this time. After being subjected to a high-temperature and high-pressure environment, the filler filled in the artificial fiber fabric melts and contacts the functional module 30, and after cooling, it is formed into a one-piece whole of the shell 10 and the functional module 30. In this way, the functional module 30 is fixed to the shell 10. However, in the high-temperature and high-pressure environment, the filler filled in the artificial fiber fabric flows after melting, and the functional module 30 is easy to deviate from the set position due to the flow of the filler when it is not fixed.

The positioning member 50 comprises at least a first panel 52 and a second panel 54. The first panel 52 and the second panel 54 are connected with each other and form a first included angle. At least one of the first panel 52 and the second panel 54 directly or indirectly defines the position of the functional module 30. In this way, the functional module 30 is fixed by the positioning member 50 to prevent the functional module 30 from being deviated due to the flow of the filler filled in the man-made fiber fabric in the high-temperature and high-pressure environment.
[0033] In a specific embodiment, the protective case 100 is used to protect a mobile phone, a tablet computer or the like.

That is, the positioning member 50 fills the notch, so that the planar thickness of the second interlayer 17 is consistent. It can be understood that the first interlayer 16 and the second interlayer 17 can be the same material layer or different material layers.
