Abstract
An ink jet type recording head includes a plurality of pressure generation chambers which are filled with ink, and piezoelectric elements which eject ink droplet through nozzle openings which are provided so as to correspond to each pressure generation chamber by applying pressure to the ink in each pressure generation chamber. The pressure generation chamber has a shape such that the piezoelectric element in the opposite side to a protrusion side in which at least a portion of the piezoelectric element protrudes out of the pressure generation chamber is deformed more easily than that in the protrusion side.
