An assembled battery wiring member for an assembled battery that plural single cells each having a positive terminal and a negative terminal are arranged in a predetermined array direction and the positive terminal of one of a pair of single cells adjacent in the array direction is connected to the negative terminal of another single cell one after another by a conductive coupling member. It includes a flat cable including plural linear conductors arranged parallel to each other and an insulating film covering the plural linear conductors, and a connecting member to connect the plural linear conductors to the coupling member. The connecting member includes a plate-shaped conductor and an insulation covering the conductor, one end of the conductor is connected to the coupling member and another end of the conductor is connected to the linear conductor through an opening formed in the insulation film of the flat cable.

Assembled battery wiring member and assembled battery module

A flexible flat cable includes a plurality of conductors arranged in parallel at predetermined intervals, an insulation layer provided on both surfaces of the conductors, a nonwoven fabric layer provided on an outer surface of the insulation layer, and a shield layer provided on an outer surface of the nonwoven fabric layer. The nonwoven fabric layer includes a nonwoven fabric having a plurality of recessed portions formed on a surface thereof, the recessed portion being enclosed by a pair of opposite long sides and a pair of opposite short sides.

Flexible flat cable

A flexible flat cable includes a plurality of conductors, a nonwoven fabric layer provided on an outer surface of an insulation layer, and a shield layer provided on the nonwoven fabric layer. The nonwoven fabric layer includes a nonwoven fabric having a plurality of recessed portions formed on a surface thereof, the recessed portions being each enclosed by two opposite long sides and two opposite short sides, and the nonwoven fabric has an embossed shape which satisfies the following relation: 2d&#x3c;b&#x3c;2a&#x3c;c where the long sides of the recessed portions are a[mm] in length, the short sides of the recessed portions are d[mm] in length, a center-to-center distance between the adjacent recessed portions parallel arranged in a direction of the short sides is c[mm], and a center-to-center distance between the adjacent recessed portions parallel arranged in a direction of the long sides is b[mm].
