An inkjet printer head includes a nozzle plate having nozzles for jetting ink; a flow path plate having flow paths for communicating with the nozzles, each of the flow paths including a pressure chamber and a resistance part having a smaller cross-sectional area than the pressure chamber, wherein piezoelectric elements having smaller horizontal areas than the flow paths are laminated on the flow path plate; and a common liquid chamber configured to guide the ink from an opening to the pressure chamber. The common liquid chamber is formed by a first member and a second member. The first member forms a top part of the common liquid chamber, and the second member forms a side surface and a bottom surface of a bottom part of the common liquid chamber by adhering to an outer wall of the first member and to an ink jetting surface of the nozzle plate. |
