PROBLEM TO BE SOLVED: To arrange signal lines easily in such a narrow region as the internal space of a display arm even when there are many numbers of signal line. SOLUTION: A single layer flexible printed board 100 in which the number of layer of signal lines is one layer has a base 110 and two portions 120, 130 extended from the base 110. The extended portions 120, 130 have lateral portions 121, 131 extended in the same direction from the base 110 respectively, and longitudinal portions 122, 132 extended in the extended direction and the about right angle direction of the lateral portions 121, 131. By bending the lateral portion 121 with a small curvature radius, and by bending the lateral portion 131 which is longer than the lateral portion 121 with a little large curvature radius, the each longitudinal portion 122, 132 whose distance from the base 110 is different overlaps, while the mutual front surfaces a and the mutual rear surfaces b of the each longitudinal portion 122, 132 are turned to the same direction respectively. In this state, the each longitudinal portion 122, 132 is let through the space of the center portion of the display arm. COPYRIGHT: (C)2008,JPO&INPIT
