Abstract:
In a disclosed recording head, a piezoelectric element applies pressure to a liquid chamber by causing an oscillating plate of the liquid chamber to be displaced. Liquid is supplied to the liquid chamber via a flow resistance part. The oscillating plate has a first portion facing a liquid chamber and a second portion facing the liquid supplying path. The piezoelectric element is longer than the liquid chamber, and an edge of the piezoelectric element on the flow resistance part side is positioned not to face the second portion of the oscillating plate but to face the first portion of the oscillating plate.
