ABSTRACT:
A composite flexible substrate (100) is constituted with an inside flexible substrate (1) and an outside flexible substrate (2) having a zigzag-shaped part (Z.sub.1), and the outside flexible substrate (2) is superposed on the inside flexible substrate (1) and is fixed at both end parts of the inside flexible substrate (1) and the outside flexible substrate (2). When the inside flexible substrate (1) is longitudinally bent, the outside flexible substrate (2) is deformed due to stretching of the zigzag-shaped part (Z.sub.1) without irregularly deforming the inside flexible substrate.
