PROBLEM TO BE SOLVED: To provide a small type and low cost inkjet head which prevents the generation of bubble from an initial stage supplying the ink to a common liquid chamber and with high reliability free from the discharge failure of the ink.SOLUTION: An inkjet head includes a nozzle 120, a nozzle plate 122, a flow path plate 125 having a pressure liquid chamber 127 storing the ink in the inside, a pressure generating element, a common liquid chamber 105 laminated on the pressure liquid chamber 127, and a through-hole supplying the ink to the common liquid chamber 105, and includes a core 165 branching the ink supplying from the through-hole in the common liquid chamber 105 to at least two directions. Hydrophilicity of a surface 181 of the side of the pressure liquid chamber 127 of the core 165 is made higher than a surface 182 of the side of the pressure liquid chamber 127 in the common liquid chamber 105. |
