PROBLEM TO BE SOLVED: To provide an inkjet recording head which can eject a high-viscosity ink at normal temperatures, and to provide an inkjet recorder. SOLUTION: If a rotary encoder 20 is rotated in a reverse rotation direction when an ink channel member 12 is preliminarily kept in a state with a deflection given in an ink ejection direction, the ink channel member 12 has the deflection direction changed to be concave from convex in the ink ejection direction. Then, if the rotary encoder 20 is normally rotated again from here, the ink channel member 12 has the deflection direction changed to be convex in the ejection direction gradually from the side near the rotary encoder 20. When this change approaches the center from both ends, the ink channel member 12 causes steep buckling reversion at a point and is suddenly deformed in the ink ejection direction. A nozzle 16 is set at nearly the center in a longitudinal direction of the ink channel member 12. COPYRIGHT: (C)2006,JPO&NCIPI
