A liquid ejection head includes a plurality of piezoelectric transducers that are configured to generate energy for respectively ejecting liquid from a plurality of ejection ports and arranged in line so as to constitute a plurality of columns and a common electrode connected to the plurality of piezoelectric transducers. The common electrode is provided with a plurality of first connection areas to which the plurality of piezoelectric transducers are connected commonly in units of columns and a second connection area that connects the plurality of first connection areas to one another. This liquid ejection head further includes a reinforcing wiring laminated on the second connection area and a wiring substrate including a drive wiring that is connected to the reinforcing wiring at at least one connection point and electrically connected to the common electrode via the connection point.
