Protective case for electronic device and method for manufacturing the same

A protective case for electronic device, comprising:

• an inner shell;
• an outer shell;
• and
• a magnetic interlayer disposed between and in contact with the inner shell and the outer shell, wherein:
• the magnetic interlayer includes an interlayer base material and a magnetic part, the interlayer base material including an inner side wall defining a through-hole, and the magnetic part fixed in the through-hole,
• the interlayer base material having a base material thickness defining a depth of the through-hole, and the magnetic part having a magnetic part thickness that is equal to the base material thickness and the depth of the through-hole,
• the interlayer base material comprising a hot-melt base material and reinforcing fiber yarn embedded in the hot-melt base material,
• the hot-melt base material disposed in contact with the magnetic part along the inner side wall of the through-hole to fix the magnetic part in the through-hole, wherein the magnetic part is fixed in the through-hole and the magnetic interlayer is flattened by applying heat and pressure to the magnetic interlayer to melt the hot-melt base material.
