1. A shielded flat cable comprising:
a plurality of ground lines disposed in a first plane;
a pair of signal lines provided between the plurality of ground lines and disposed in the first plane, the pair of signal lines including a first pair of signal lines and a second pair of signal lines;
an insulating layer that covers the plurality of ground lines and the pair of signal lines; and
at least one Shield layer that covers the insulating layer,
wherein the first pair of signal lines includes a first signal line and a second signal line adjacent to the first signal line,
the second pair of signal lines includes a third signal line and a fourth signal line adjacent to the third signal line, and
the plurality of ground lines include a first ground line that is provided between the second signal line and the third signal line, and
wherein, in a cross section perpendicular to a longitudinal direction of the shielded flat cable,
a minimum distance between the first signal line and the second signal line is smaller than a minimum distance between the second signal line and the first ground line, and
a minimum distance between the third signal line and the fourth signal line is smaller than a minimum distance between the third signal line and the first ground line.
