These recessed angled portions are provided in three or more numbers in one side of the flexible circuit board. In more detail, the flexible circuit board also includes at least one narrowed portion for narrowing the width of the flexible circuit board, and the narrowed portions are arranged opposed with each other in both sides of the flexible circuit board. Moreover, the narrowed portion includes at least any of the stepped portion in the shape of the stepping area and the cutting portion in the shape of letter V or U. In one side of the flexible circuit board, three or more stepped portions and cut-away portions in total are arranged. <P>COPYRIGHT: (C)2007,JPO&INPIT |
