Shielded flat cable

A shielded flat cable comprising:

• one or more ground wires arrayed, the ground wires being parallel to each other;
• one or more signal wires arrayed parallel to the one or more ground wires;
• an insulating layer covering the one or more ground wires and the one or more signal wires;
• and
• a shield layer provided on an outer surface of the insulating layer,
• wherein the insulating layer includes a plurality of openings of which bottoms are respectively an upper surface and a lower surface of each of the one or more ground wires in a cross-section orthogonal to a longitudinal direction of the one or more ground wires, and
• wherein the one or more ground wires and the shield layer are electrically coupled at the plurality of openings, and each of the one or more signal wires is surrounded by the one or more ground wires and the shield layer,
• wherein a resin interlayer is interposed between the insulating layer and the shield layer, and
• wherein the resin interlayer extends in an array direction in which the one or more signal wires are arrayed side by side, such that one end of the resin interlayer in the array direction is situated, in the array direction, at a space between one signal wire among the one or more signal wires and one ground wire among the one or more ground wires.
