1. A shielded flat cable comprising:
a plurality of conductors arrayed together in parallel along a first plane;
a resin insulating layer including a first resin insulating layer and a second insulating layer, the first plane being sandwiched between the first resin insulating layer and the second insulating layer, and the first resin insulating layer and the second insulating layer covering the plurality of conductors;
a shield layer that covers an outer surface of the resin insulating layer and that includes an adhesive; and
a pair of flame-retardant resin films that cover an outer surface of the shield layer,
wherein the pair of resin films have a first bonding section and a second bonding section, the first bonding section being disposed at a first end of the resin insulating layer, and the second bonding section being disposed at a second end of the resin insulating layer,
wherein the pair of resin films are bonded in the first bonding section such that the pair of resin films are in contact with each other at a first interface,
wherein the pair of resin films are bonded in the second bonding section such that the pair of resin films are in contact with each other at a second interface,
wherein the outer surface of the shield layer has a first portion that contacts the first interface and a second portion that contacts the second interface, the first portion being perpendicular to the first interface, and the second portion being perpendicular to the second interface,
wherein the shield layer has a third bonding section where the adhesive is bonded to each other at a third interface, and
wherein the third interface is separate and distinct from the first interface and the second interface.
