PROBLEM TO BE SOLVED: To provide a liquid droplet ejection head in which an adhesion layer is prevented from being damaged in cleaning. SOLUTION: The liquid droplet ejection head is equipped with ejection ports for ejecting liquid droplets, individual liquid chambers communicating with the ejection ports, pressure generating elements which apply a pressure to the liquid in the individual liquid chambers, and a pair of electrodes. The adhesion layer is provided at least between one of the electrodes and the pressure generating element. A peripheral part of the adhesion layer is formed of a material different from that of a center part of the adhesion layer. COPYRIGHT: (C)2008,JPO&INPIT
