Abstract: A protective case adapted to be mounted on an electronic device is provided, wherein the electronic device is adapted to perform wireless signal transmission, and has a front surface for usage. The protective case is adapted to surround a periphery of the front surface, and has a frame which surrounds the periphery of the front surface when the protective case is mounted on the electronic device. The protective case includes a core material and a plated coating. The core material includes a metal material. The plated coating covers a surface of the core material, and has a thickness between 15 ?m and 25 ?m. Materials of the plated coating include a metallic oxide and an alloy oxide. Specifically, with the metallic oxide and the alloy oxide, the plated coating separates the core material from the exterior, and therefore provides an anticorrosion function, as well as prevents external interferences.

Abstract: A protective case includes a first half frame, which has a first body portion and a first strengthened portion connected to two different positions on the first body portion, and a second half frame, which has a second body portion and a second strengthened portion connected to two different positions on the second body portion. Two first abutting portions are provided at two different positions on the first body portion, and the first strengthened portion has a second abutting portion. Two third abutting portions adapted to abut against the first abutting portions are respectively provided at two different positions on the second body portion. The second strengthened portion has a fourth abutting portion adapted to abut against the second abutting portion. Whereby, the first body portion and the second body portion form a complete frame, which surrounds an outer periphery of an electronic device to provide a protective effect.
