A droplet ejection head according to the present invention includes a layered body made up of a plurality of metal plates in which at least a part of a liquid passage is formed, and an ejection face in which an ejection port provided at one end of the liquid passage and ejecting an ink droplet is formed. The plurality of metal plates in the layered body include m metal plates whose lengthwise directions form the same angle with a rolling direction thereof, and n metal plates whose lengthwise directions form the same angle with the rolling direction. The angle formed between the lengthwise direction of the m metal plates and the rolling direction is different from the angle formed between the lengthwise direction of the n metal plates and the rolling direction.
