The present disclosure relates to the technical field of film sticking, more particularly to a sticking film, a film-sticking tool and a film-sticking assembly. The sticking film includes a tempered film for attaching to the screen of an electronic product, and a release film layer attached to the tempered film. The release film layer is an electrostatic layer, the release film layer and the tempered film are separated when pasting, and the side of the release film layer that is attached to the tempered film generates static electricity to attract dust on the screen. Thus, static electricity can be generated when the release film layer and the tempered film are separated, which can attract dust on the screen of electronic products and clean the screen, and avoids dust particles from scratching the screen due to direct wiping of the screen, resulting in damage to the performance of the screen.
