来る。As described above, in the present invention, the terminals of the electrical components attached to one side of the board are arranged at a predetermined height from the board, and the central part of the flexible printed circuit board closely attached to one side of the board is connected to the terminals. The flexible printed circuit board has a semi-circular notch in the center thereof, and a tongue piece located inside the notch. Since the soldering of a flexible printed circuit board is a structure in which only the central part of the flexible printed circuit board is raised from one side of the board and soldered to the terminal, unlike conventional flexible printed circuit boards, the central part of the flexible printed circuit board is S
``There is no need to heave it into a hemispherical shape, and the tongue piece can be soldered to the terminal very easily, making the soldering process easier and more reliable.
