PROBLEM TO BE SOLVED: To lower the ink ejection voltage while stabilizing the flying characteristics of ink by arranging an ink ejecting part such that a dielectric ejection member is assisted by an assisting member, a coating member is arranged to hold the ejection member between and an ejection electrode is wrapped in the coating member. SOLUTION: An ink ejection cell 3 comprises ejection electrodes 31 arranged on the opposite sides of a dielectric ejection member 32. The ejection member 32 is formed on an assisting member 19 of polyimide, or the like, by production process of ink jet recording head while projecting from the end face of an insulating substrate 17 in order to enhance the field at the forward end thereof and the ejection electrodes 31 is wrapped in the coating member 4. More specifically, the gap between the adjacent ink ejection cells 3 is filled with the coating member 4. According to the structure, the ink ejection voltage can be lowered while stabilizing the flying characteristics of ink.
