A network concentrator is mounted on a mounting surface using a mounting piece. The network concentrator 1 is given a mounting hole in a mounting part. If the mounting surface is not magnetic, a protrusion such as a screw provided on the mounting surface is inserted into the mounting hole. If the mounting surface is magnetic, on the other hand, a mounting piece is used. The mounting piece has such a form as to be inserted into the mounting hole, and is provided with a magnet. The magnet is attached to the mounting surface, and a part of the mounting piece is inserted into the mounting hole, thereby mounting the network concentrator on the mounting surface.
