A wiring member for a liquid ejection head enables reducing the size of the liquid ejection head. A flexible printed circuit has on one end a plurality of individual electrode wiring terminals corresponding to individual element electrode terminals of piezoelectric elements; individual electrode wires corresponding to the individual electrode wiring terminals; a common electrode wiring terminal corresponding to a common electrode terminal of the piezoelectric elements; and a common electrode wire corresponding to the common electrode wiring terminal. The individual electrode wiring terminals, common electrode wiring terminal, and individual electrode wires are disposed on one side of the flexible printed circuit, and the common electrode wire is disposed on the other side of the flexible printed circuit.
