An optical transceiver that provides an inner metal cover in addition to a metal cover and a frame is disclosed. The inner cover includes a ceiling, a front skirt bent downward at a front edge of the ceiling, sides bent downward at both side edges of the ceiling, and a pair of arms extending rearward from respective side ends of the ceiling. The ceiling makes an obtuse angle with respect to the front skirt when the arms are not assembled with the frame, and shapes in convex protruding outward when the metal cover is not assembled with frame and. Assembling the inner cover and the metal cover with the frame, the inner cover comes in securely contact with the metal cover.
