Abstract
A droplet ejection head according to the present invention includes a layered body made up of a plurality of metal plates, and an ejection face. The plurality of metal plates in the layered body include n metal plates whose lengthwise directions form the same angle with a rolling direction thereof. The n metal plates include a first stress plate and a second stress plate. The first stress plate has internal stress which forces the metal plate to bend along its lengthwise direction so as to make it protrude toward a ejecting direction. The second stress plate has internal stress which forces the metal plate to bend along its lengthwise direction so as to make it protrude toward a direction opposite to the ejecting direction.
