A metal shell (50) of a mobile terminal and its preparation method and a mobile terminal comprise the following steps: forming an insulating film (20) on the outer surface of the metal shell body (10); cutting the metal shell body (10) into two parts of electric insulation; filling an insulating material (30) in a gap (11) formed by cutting, and the insulating material (30). The material (30) combines and combines the two parts of the split metal shell body (10) into one body. In the above-mentioned technical scheme, the consistency of the outer surface of the whole metal shell (50) is achieved by forming an insulating film (20) on the outer surface of the metal shell body (10) to block the difference between the insulating material (30) on the metal shell body (10) and the metal shell body (10), and the gold produced by the above-mentioned preparation method is also realized. The case (50) forms a hidden breakpoint, which greatly improves the flexibility of smartphone antenna design with all-metal case.
