<P>PROBLEM TO BE SOLVED: To provide a liquid ejection head that can enhance the rigidity of a pressure chamber. <P>SOLUTION: The liquid ejection head includes a plurality of pressure chambers 3 communicating to an ejection orifice 10 ejecting liquid and for storing the liquid ejected from the ejection orifice 10 and ejects the liquid from the ejection orifice 10 in accordance with expansion and contraction of a piezoelectric element constituting an inner wall of the pressure chamber 3. A plurality of recess parts 4a and 4b are disposed around the pressure chamber 3, and a piezoelectric member 34 is present between at least one of the recess parts and the pressure chamber 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
