Abstract
A piezoelectric vibration element is abutted against a vibration plate such that a central point C1 of the piezoelectric vibration element by is displaced by a distance .DELTA.d toward a nozzle opening from a central point C2 of a length L of an effective displacement region on vibration plate, whereby the displacement of the piezoelectric vibration during operation of the element is particularly efficiently transmitted to ink in the vicinity of the nozzle opening.
