Patent ID: 8182067

Claim:
A droplet discharge head, comprising: a plurality of elongate liquid reservoirs which hold a liquid; a channel through which the liquid is guided to the liquid reservoirs, the liquid reservoirs extending from the channel; a plurality of nozzles respectively located at ends of the liquid reservoirs located away from the channel; and a plurality of driving elements respectively located in the liquid reservoirs beneath the nozzles and which change the pressure in the liquid reservoirs so as to respectively discharge droplets of the liquid contained in the liquid reservoirs through the nozzles, wherein, the channel and the liquid reservoirs are aligned such that the liquid flows in the channel and in the liquid reservoirs along a same direction, and for each liquid reservoir and its respective nozzle, a wall surface of the liquid reservoir and a wall surface of the nozzle are coincident and arranged in a continuous line at a side opposite the channel with respect to the center of the nozzle as seen in a cross-sectional view through a central axis of the nozzle so as not to have a recess or a step portion.
