1. A protective element-mounted flexible flat cable comprising:
a plurality of conductive wires, one of the plurality of conductive wires includes a first portion and a second portion;
an insulating sheet covering the plurality of conductive wires; and
a protective element that is disposed between the first portion of the one of the plurality of conductive wires and the second portion of the one of the plurality of conductive wires and is configured to limit an overcurrent flowing through the at least one of the conductive wires,
wherein the insulating sheet comprises an upper-side insulating sheet disposed above the plurality of conductive wires, and a lower-side insulating sheet disposed below the plurality of conductive wires,
each of the upper-side insulating sheet and the lower-side insulating sheet includes an opening overlapping the protective element in a thickness direction of the insulating sheet, and
the protective element includes a current limiting element and a substrate, the substrate disposed below the lower-side insulating sheet,
wherein the current limiting element is directly disposed on an upper surface of the substrate which is disposed below the lower-side insulating sheet, while the current limiting element is free of direct contact with the upper-side insulating sheet and the lower-side insulating sheet.
