PROBLEM TO BE SOLVED: To realize an increase in density of nozzles and refill performance. SOLUTION: The problem is solved by providing a liquid ejection head having a plurality of ejection outlets for ejecting liquid, a plurality of pressure chambers respectively communicating with the plurality of ejection outlets, piezoelectric elements provided in the side opposite to the side in which the ejection outlets of the plurality of pressure chambers are formed for respectively deforming the plurality of pressure chambers, a common liquid chamber which is provided in the side opposite to the side in which the ejection outlets of the pressure chambers are formed, formed to have a plurality of heights relative to the plane in which the piezoelectric elements are disposed, and feeds the liquid to the plurality of pressure chambers, and a wiring member including electrodes which are for driving the piezoelectric elements and formed so that at least a part of them arises approximately vertically relative to the plane in which the piezoelectric elements are disposed in the common liquid chamber.
