PROBLEM TO BE SOLVED: To provide a low cost and space-saved liquid drop ejection head and an inkjet recorder. SOLUTION: This liquid drop ejection head 0 comprises one or more nozzle holes 31, pressurizing liquid chambers 11 each communicating with each of nozzle holes, a common liquid chamber 12 communicating with the pressurizing liquid chambers 11, and a diaphragm 13 forming at least one wall of the pressurizing liquid chamber 11. The head 0 ejects a liquid drop by applying energy to a liquid in the pressurizing liquid chamber 11 by deforming the diaphragm 13. A deformable plate 14 of which the deforming amount is greater than that of the diaphragm is provided to one wall of the common liquid chamber 12, and an air pressure correction chamber 23 is provided opposite to the deformable plate 14.
