A droplet discharge head includes a nozzle substrate having a nozzle opening for discharging a liquid as a droplet; a flow path substrate having a flow path for the liquid, the flow path communicating with the nozzle opening; and a diaphragm constituting a wall surface of the flow path. The nozzle substrate, the flow path substrate, and the diaphragm are bonded together in layers using an adhesive, and a liquid-resistant film resistant to the liquid is continuously formed on surfaces of the nozzle substrate, the flow path substrate, and the diaphragm, the surfaces being in contact with the liquid.
