PROBLEM TO BE SOLVED: To provide an electromechanical conversion element capable of improving reliability while reducing usage of lead, a liquid droplet discharge head, and a liquid droplet discharge device.SOLUTION: A recording head 94 of an inkjet recording device 80 includes an electromechanical conversion element 30. The electromechanical conversion element 30 includes a lower electrode layer 34 formed on a vibration plate 31, an electromechanical conversion layer 36 formed on the lower electrode layer 34, and an upper electrode layer 37 formed on the electromechanical conversion layer 36. The electromechanical conversion layer 36 is mainly composed of BaTiO3 and presents distortion caused by field application. A seed layer 35 is arranged on the lower electrode layer 34. |
