The invention provides a flash lamp shade, mobile terminal equipment and a casing of the mobile terminal equipment. The flash lamp shade comprises a lamp shade base, wherein the lamp shade base is a light transmitting body, the light incoming surface of the lamp shade base comprises a first surface area, a second surface area and a third surface area, the first surface area and the third surface area are arranged at an interval, and the second surface area is located between the first surface area and the third surface area; the first surface area is used for allowing an ink layer to be attached to; a flow resisting structure is arranged on the second surface area and used for preventing ink in the first surface area from overflowing to the third surface area; lines are arranged on the third surface area. According to the flash lamp shade in the scheme, the ink on the surface of the first surface area is prevented from overflowing to the third surface area by the aid of the flow resisting structure, particularly, the ink is prevented from flowing to the third surface area when printing deviation occurs or the ink extends outwards in the printing process, so that technological defects of a product are effectively reduced, light transmission of the third surface area is guaranteed, and reliable light focusing function of the lines on the third surface area is guaranteed.
