PROBLEM TO BE SOLVED: To provide a droplet ejecting head which minimizes a dispersion in fluid resistance values of respective liquid resistive flowing sections, achieves sufficient ink feeding to nozzles even in the case of high-frequency ejection, and suppresses a degradation in image quality caused by an ejection dispersion. SOLUTION: In the droplet ejecting head or a recording head 14, each pressurized liquid chamber 51b is connected to a liquid inflow port 51j for allowing inflow of liquid from the outside, via the liquid resistive flowing section 56 which is narrower than the pressurized liquid chamber 51b, and pressure generated in the pressurized liquid chamber 51b can be efficiently transferred to the nozzle without dissipation in a direction of the liquid inflow port 51j. Then by setting a lengthwise dimension L of the liquid resistive flowing section 56 to 400μm or less, the fluid resistance value of the liquid resistive flowing section 56 is decreased, and therefore sufficient ink feeding to the nozzles is achieved even in the case of the high-frequency ejection, thereby suppressing the ejection dispersion.
