ABSTRACT:
A liquid droplet ejection head having: a vibrating plate at which is formed a piezoelectric element which deforms when voltage is applied; a wiring board disposed above the piezoelectric element, an electric wire for deforming the piezoelectric element being disposed at the wiring board; a liquid storage chamber provided at a side opposite to the piezoelectric element, with the wiring board sandwiched therebetween; a pressure chamber provided at a side opposite to the wiring board, with the vibrating plate sandwiched therebetween; an ejection opening that ejects liquid droplets from the pressure chamber; a liquid supply opening that supplies liquid within the liquid storage chamber to the pressure chamber; and an electrical connection portion that passes through the wiring board and electrically connects the piezoelectric element and the electric wire through the liquid supply opening, is provided.
