Abstract
A liquid jetting apparatus includes: a flow passage structure having nozzles aligned in a first direction, pressure chambers aligned in the first direction to correspond respectively to the nozzles, and a vibration film covering the pressure chambers; piezoelectric elements arranged on the vibration film to correspond respectively to the pressure chambers; and traces extending along a planar direction of the vibration film to correspond respectively to the piezoelectric elements. Each of the piezoelectric elements has a piezoelectric film arranged to cover the pressure chambers, and an individual electrode provided on the piezoelectric film to face a central portion of one of the pressure chambers and extending in a second direction intersecting the first direction. Within each area, of the vibration film, facing one of the pressure chambers, each of the traces extends from a connecting portion of the individual electrode along a third direction intersecting the second direction.
