The cover and the electronic device

The invention relates to a shell cover and an electronic device, wherein the shell cover is used for covering an opening of the shell of the electronic device. The shell cover comprises a cover body and a capture structure. The cover body is provided with an inner surface, and when the shell cover covers the opening, the inner surface faces to the inside of the shell, the capture structure is formed on the inner surface to capture objects falling on the inner surface. The capture structure can be an adhesion layer or comprises a protruding structure; and when the capture structure is the adhesion layer, the capture structure is used for adhering to the objects on the inner surface, and when the capture structure comprises the protruding structure, the objects can be limited in the capturestructure by the protruding structure. By adopting the shell cover and the electronic device, the occurrence that users are hurt due to falling objects when replacing parts can be avoided.
