Disclosed is a cover structure for a notebook computer's built-in camera. The cover structure includes a U-shaped lower plate (102) fixedly provided on an upper surface of a monitor frame at a predetermined distance from a camera, and an upper plate (104) slidably coupled to an upper surface of the lower plate (102) so as to open and close the camera, whereby one side of the lower plate is an open structure so that a user is able to easily and stably perform a sliding operation through a wide manipulation range in a horizontal direction, thereby easily physically closing the camera, and the upper and lower plates have a simple structure and shape, thereby providing easy manufacture and assembly of the cover structure.
