Abstract
A liquid ejecting head includes a flow channel forming substrate having pressure generation chambers communicating with a nozzle opening and arranged in parallel along a lateral direction. A piezoelectric element is provided on one surface of the flow channel forming substrate in correspondence to the pressure generation chamber, and has a first electrode, a piezoelectric layer provided on the first electrode and a second electrode provided on the piezoelectric layer. In a direction intersecting with the arrangement direction of the pressure generation chambers, in boundaries between an active section that is a substantial driving section and an inactive section that is not a substantial driving section of the piezoelectric layer, the first electrode includes a taper section of which a width is gradually decreased toward the boundary from the active section side.
