<p>PURPOSE:To maintain the long lifetime of a flexible flat cable resisting repeated bending and tensile stress due to the repeated turning operation of a handle, and make the thickness of the cable small by applying the predetermined relationship to each thickness of a polyester film layer and an adhesive layer. CONSTITUTION:The thickness TA of a polyester film layer 1 and the thickness TP of an adhesive layer 2 have a relationship of (TA+TP)<=105mum, 1.6>=TA/TP>=1.0 and TP>=38mum. According to the aforesaid construction, a flexible flat cable of durability against rotation can be furnished within the thickness of the aforesaid limit value.</p> |
