PROBLEM TO BE SOLVED: To obtain a droplet discharge head a droplet discharge device, and a droplet discharge head manufacturing method, capable of obtaining densified nozzles, cubic capacity of a reservoir which is enough to prevent crosstalk while securing the depth of a discharge chamber. SOLUTION: The droplet discharge head has a channel substrate 2 where a nozzle substrate 1 having a plurality of nozzle holes 11, a plurality of nozzle communication holes 21 communicating with the nozzle holes 11, a plurality of discharge chamber concavities 22a forming a discharge chamber 22 communicating with the nozzle communication holes 21 and discharging droplets from the nozzle holes 11 by generating pressure in the chamber, a reservoir 24 collecting droplets to be supplied to the discharge chamber concavities 22a, and a plurality of supply ports 23 making the discharge chamber concavities 22a communicate with the reservoir 24 are formed and a vibration diaphragm substrate 3 having a diaphragm 31 generating pressure in the discharge chamber concavities 22a of the channel substrate 2 and a pressure generation means to give pressure variations to the discharge chamber 22 by deforming the vibration diaphragm 31.
