摘要： 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 (11) occurs during liquid ejection. This is because the liquid ejection head allows the thermal expansion to influence supported valves (6) only to a small extent, and a highly accurate and stable adhesion state to be obtained. To this end, first holes (19), second holes (18) and slits (20) are provided in the valve supporting member.
