Disclosed is a liquid ejection head capable of performing a stable ejection operation at high speed even when thermal expansion of a valve supporting member occurs during liquid ejection. This is because the liquid ejection head allows the thermal expansion to influence supported valves only to a small extent, and a highly accurate and stable adhesion state to be obtained. To this end, first holes, second holes and slits are provided in the valve supporting member.
