A camera, which is waterproof, having a relatively complicated three-dimensional configuration in which a cover thereof is constituted by a plurality of cover elements. A top cover 20, a front cover 30 and a side cover 40 are connected at the inside to form a first cover group. Then a main body 50 of the camera is connected to the first cover group to form a half completed body. A second cover group which is constituted by connecting a rear cover 60 to a bottom cover 70, and a lid 80, are connected to the half completed body. Each connection part therebetween has a rib and a groove corresponding to the rib. A packing is inserted into the groove to seal the groove and rib. Thus, a cover structure with a relatively complicated three-dimensional configuration as having a projecting grip, a pop-up flash, or the like, is possible to be made. At time of repair, for example, it is possible to get an access to the inner mechanisms of the camera, only by removing the second cover group from the camera body.
