Abstract
A liquid ejection head includes an element substrate for ejecting a liquid, an integrated circuit board outputting a control signal for controlling the element substrate, and an electrical wiring board connected electrically to the element substrate. The electrical wiring board has a signal line connector to which control signals are inputted and electrical wiring board connectors to which an electric signal for driving the liquid ejection head is inputted. The signal line connector and the electrical wiring board connectors are disposed on opposite sides to each other relative to a center line extending orthogonally to a longitudinal direction of the electrical wiring board.
