The present invention provides a liquid droplet ejecting head including: a pressure chamber connected to a nozzle ejecting liquid-droplets; a vibrating-plate forming one portion of the pressure chamber; a lower-electrode formed on a surface of the vibrating-plate, and exhibiting one polarity; a piezoelectric body of flexurally-deformable, formed on a surface of the lower electrode, and disposed at a position facing the pressure chamber with the vibrating-plate therebetween; and an upper-electrode formed at a surface of the piezoelectric body opposite the surface at which the lower-electrode is formed, the upper-electrode exhibiting another polarity, when viewed from a direction perpendicular to the surface of the lower-electrode, the piezoelectric body being provided further toward an inner side than a peripheral wall of the pressure chamber, and the lower-electrode being of a size such that one portion thereof overlaps with the peripheral wall of the pressure chamber, and being individuated per each piezoelectric body.
