Liquid ejection head and liquid ejection apparatus |
| abstract |
A liquid ejection head comprising a flow-channel-containing substrate having pressure generating chambers communicating a nozzle opening and a piezoelectric element including a first electrode, a piezoelectric layer formed above the first electrode, and a second electrode formed above the piezoelectric layer. The piezoelectric layer includes an active portion which is substantially driven, a non-active portion which is not substantially driven, and a low dielectric material layer which has a dielectric constant lower than that of a center portion of the active portion and which is in the active portion side of the boundary between the active portion and the non-active portion. |
