<p><P>PROBLEM TO BE SOLVED: To provide a flexible printed cable capable of transmitting digital signal of higher speed than a conventional one by a single mode. <P>SOLUTION: A signal line and a grounding line are alternately arranged on the surface 21 and rear face 22 of a polyimide film 23. The width W2 of the grounding lines 41-45 are 5 times of the width 31 of the signal lines 31 etc. and the grounding lines 42, 44 on the surface side 21 are overlapped with the grounding lines 43, 45 on the rear side 22. Each signal line 31 etc. has a structure closely resembling the structure of a micro strip line. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
