Abstract
A differential signal transmission circuit comprises: an insulating layer; two signal lines provided in parallel on one surface of the insulating layer; a GND line formed on each of outer sides of the two signal lines on the one surface of the insulating layer; and a wiring line layer formed on the other surface of the insulating layer, the differential signal transmission circuit being configured by a double-sided flexible printed circuit board, the signal lines, the GND line and the wiring line layer being formed by a semi-additive method on the insulating layer, and the signal line and the GND line being formed such that a distance S between the two signal lines is greater than a distance D between the signal line and the GND line.
