1. A wiring material including a flexible circuit board in which a plurality of batteries arranged in one direction is connected to one another via a bus bar and an arrangement direction of the plurality of batteries is a longitudinal direction of the flexible circuit board, comprising:
a narrow connecting portion connected to the bus bar;
a main body that is connected to the connecting portion and includes a portion wider than the connecting portion;
an electrode connected to the bus bar; and
a wiring, a part of the wiring being formed so as to be connected to the electrode from the main body via the connecting portion, wherein
the connecting portion has a longitudinal extending portion that projects from the main body in the longitudinal direction and extends in the longitudinal direction,
the connecting portion has a cross-extending portion that extends from the longitudinal extending portion in a direction intersecting the longitudinal direction and is connected to the bus bar, a length of the longitudinal extending portion is longer than the cross-extending portion, and
the part of the wiring is formed so as to be connected to the electrode from the main body via the longitudinal extending portion and the cross-extending portion.
