An anti-wear FFC (flexible flat cable) according to the present invention is made up of a plurality of covered wires parallel to each other in side-by-side relationship. The anti-wear FFC is folded and forms a plurality of planes lengthwise. The anti-wear FFC includes a base plane and a wing plane connected to the base plane. The base plane and the wing plane forms an angle therebetween. The stress of the wind plane connected to the base plane prevents the FFC from protruding upwards under elasticity and further moves following a signal collecting unit smoothly.
