A liquid droplet ejection head includes: a first substrate having a pressurizing chamber with a nozzle aperture that ejects liquid droplets, and a first surface on which is formed a first wiring electrically connected to the drive element; a second substrate disposed on the first surface of the first substrate and covering the driven element, the second substrate having a second surface and a side surface, the second surface facing in a same direction as the first surface of the first substrate and on which is formed a second wiring, the side surface on which is formed a third wiring that combines the first wiring and the second wiring; a semiconductor element disposed on the second surface of the second substrate, and which drives the driven element; and plating that electrically connects the first wiring, the second wiring, the third wiring, and a connection terminal of the semiconductor element. |
