PROBLEM TO BE SOLVED: To provide a droplet discharging head improved in the handleability by heightening the rigidity of commonly-supplying-channel-forming-members and which has high operating reliability with stabilized discharging characteristics. SOLUTION: In the droplet discharging head including: a plurality of nozzles 1 arranged in a line, pressure chambers 3 provided respectively and individually communicating with each nozzle 1; a pressure generating means 17 for giving the change of pressure to the pressure chambers 3; individually supplying flow channels 4 individually provided communicating with the pressure chambers 3; and a commonly-supplying-flow-channel-forming-member 10, in which a commonly-supplying-flow-channel 8 communicating with the individually supplying flow channels 4, so as to introduce the liquid supplied through the commonly-supplying-flow-channel 8 to the pressure chamber 3 in order to give the change of pressure with the pressure generating means 17 to the pressure chamber 3 via the individually-supplying-flow-channel 4 for discharging droplets from the nozzles 1, a plurality of grating parts 9 extending normal to the arranging direction of nozzles are formed at the predetermined space intervals in the arranging direction of the nozzles in the commonly-supplying-flow-channel 8 of the commonly-supplying-flow-channel-forming-member 10.
