Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inkjet print head of which the ejection performance can be improved.SOLUTION: This inkjet print head 1 includes a pressurizing chamber 20 extending in an ink flowing direction 21, a diaphragm 5 which is deformed so as to change the volume of the pressurizing chamber 20, a silicon substrate 2 which supports the edge portion of the diaphragm 5 and demarcates the diaphragm 5 and the pressurizing chamber 20, and a piezoelectric element 6 which is formed to be in contact with the surface of the diaphragm 5 at the side opposite to the pressurizing chamber 20. The inkjet print head 1 further includes a beam member 23 as an intermediate support member which has a support edge portion 23a extending along the diaphragm 5 so as to intersect with the ink flowing direction 21 at a midway position in the pressurizing chamber 20 in the ink flowing direction 21 and supports the diaphragm 5 by being in contact with the diaphragm 5 at the support edge portion 23a.
