PROBLEM TO BE SOLVED: To provide a liquid droplet ejection head which can prevent defective sealing by adjusting an electrode width of an electrode part (terminal part) formed at a glass substrate and eliminating parts exposed at both sides of the electrode part in a sealing part, and to provide a liquid droplet ejector, a manufacturing method for the liquid droplet ejection head and a manufacturing method for the liquid droplet ejector. SOLUTION: The liquid droplet ejection head comprises a cavity substrate, the glass substrate in which the electrode part (discrete electrodes, a lead part and the terminal part) is formed, and a nozzle substrate. A plurality of recesses 9 for forming the discrete electrode 8 and the lead part 10 separately, and a concave surface 26 for forming the terminal part 11 are formed in the glass substrate. The terminal part 11 is formed from the concave surface 26 towards the recess 9 to ride on a glass partition between the recesses 9. COPYRIGHT: (C)2008,JPO&INPIT
