PROBLEM TO BE SOLVED: To provide an ink jet recording head in which air bubbles are prevented from accumulating in the corner part of a pressure generation chamber, and improvement in discharge of accumulated babbles and the durability of a vibration plate are contrived, and provide further a method for manufacturing the ink jet recording head as well as an ink jet recording device. SOLUTION: This ink jet recording head comprises a piezoelectric element 300 formed in a region corresponding to a pressure generation chamber 12 through an elastic membrane constituting a part of the pressure generation chamber 12 communicating with a nozzle port by a membrane formation and lithographic process. In this ink jet recording head, an adhesive layer 14 is formed in a corner part formed of the elastic membrane 50 and faces 15, 16 constituting the peripheral wall of the pressure generation chamber 12. Thus it is possible to prevent air bubbles from accumulating in the corner part and enhance the performance of discharge of accumulated bubbles. Further, the durability of the vibration plate is enhanced as the stress concentrating part of the vibration plate is reinforced.
