摘要：
A droplet discharge head includes a nozzle plate provided with a nozzle opening which discharges an ink drop, an actuator substrate which forms a pressurized liquid chamber communicating with the nozzle opening, and is provided with a pressure generator changing a pressure in the pressured liquid chamber, and a common liquid chamber-forming substrate which forms a common liquid chamber to which ink which is supplied to the pressurized liquid chamber is supplied, the common liquid chamber-forming substrate includes a first plate made of a metal material, a second plate made of a resin material provided on one surface of the first plate, and a third plate made of a resin material provided on the other surface of the first plate, and the first plate, the second plate, and the third plate being integrally molded in a thickness direction.
