Abstract: A fixing device for accurately fixing an optical assembly to a rear housing of an electronic device fixes the optical assembly in a predetermined position and includes a cover plate. The cover plate defines a hole and a limiting portion. The hole corresponds to a photosensitive portion of the optical assembly and the photosensitive portion is configured to protrude out of the cover plate. The limiting portion is configured to limit a movement of the optical assembly away from the rear housing before being fixed in position. The fixing device fixes the optical assembly in the predetermined position so that the assembly accuracy and efficiency are improved. An optical module including the fixing device, and an electronic device including the optical module are also provided.
