Abstract
A liquid discharge module includes a nozzle plate, a housing, a valve, and a mover. The nozzle plate has a first face, a second face opposite to the first face, and a nozzle hole. The nozzle hole has at least two different inner diameters between the first face and the second face. The housing has a liquid chamber facing the first face of the nozzle plate and communicating with the nozzle hole. The housing supports the nozzle plate. The valve is disposed in the liquid chamber. The valve contacts the first face of the nozzle plate to form a sealed portion between the valve and the nozzle plate to close the nozzle hole. The mover moves the valve in a contact-separation direction between a contact position at which the valve contacts the nozzle plate and a separation position at which the valve is separated from the nozzle plate.
