Abstract: A liquid discharge head includes: a nozzle plate having multiple nozzles from each of which a liquid is to be discharged; a housing supporting a peripheral edge of the nozzle plate; a liquid channel between the nozzle plate and the housing; and a coupling portion coupling an inner region of the peripheral edge of the nozzle plate and the housing.

Abstract: A discharge head includes a nozzle, a valve body, a piezoelectric element, and a first biasing unit. The nozzle is configured to discharge liquid. The valve body is configured to open and close the nozzle. The piezoelectric element is configured to drive the valve body. The first biasing unit is disposed in parallel with the piezoelectric element. The piezoelectric element is configured to drive the valve body in a direction to open the nozzle when a voltage is applied to the piezoelectric element. The first biasing unit is configured to bias the valve body in the direction to open the nozzle.
