Wired circuit board and electronic device

Abstract

A wired circuit board has an insulating layer extending in a longitudinal direction, a conductive layer having a plurality of signal wirings covered with the insulating layer and arranged in mutually spaced-apart and parallel relation in a perpendicular direction to the longitudinal direction and a thickness direction of the insulating layer, and connecting terminals provided on both longitudinal ends of each of the signal wirings and exposed from the insulating layer, and a ground layer covered with the insulating layer and formed to surround each of the signal wirings in a perpendicular direction to the longitudinal direction. A slit along the longitudinal direction is formed between each of the signal wirings in the insulating layer.

       3 . An electronic device comprising:
 a first casing;   a second casing connected to the first casing;   a connecting member for connecting the first casing and the second casing so as to be relatively rotatable; and   a wired circuit board comprising:
 an insulating layer extending in a longitudinal direction, 
 a conductive layer having a plurality of signal wirings covered with the insulating layer and in mutually spaced-apart and parallel relation in a perpendicular direction to the longitudinal direction and a thickness direction of the insulating layer, and connecting terminals provided on both longitudinal ends of each of the signal wirings and exposed from the insulating layer, and 
 a ground layer covered with the insulating layer and formed to surround each of the signal wirings in a perpendicular direction to the longitudinal direction, the insulating layer being formed with a slit between each of the signal wirings along the longitudinal direction, wherein 
   each of the connecting terminals on one side in a longitudinal direction is connected to an electronic component of the first casing;   each of the connecting terminals on the other side in the longitudinal direction is connected to an electronic component of the second casing; and   each of the signal wirings is disposed around the connecting member and is arranged parallel along a direction in which the first casing and the second casing relatively rotate.
