PROBLEM TO BE SOLVED: To provide a liquid droplet discharging head which can prevent the liquid filling speed from dropping and attain high throughput while reducing the crosstalk. SOLUTION: The liquid droplet discharging head 64 includes a plurality of nozzles 90 for discharging the liquid droplet to a recording medium, a plurality of pressure chambers 84 which are prepared for each nozzle 90, connected with communication and filled up with liquid, a diaphragm 86 which is actuated by a pressure generating element 88 and makes the volume of each pressure chamber 84 changed, a common liquid chamber 60 wherein the liquid supplied to each pressure chamber 84 is stored, a liquid channel 94 for making the communicating connection between each pressure chamber 84 and the common liquid chamber 60, a plurality of branch channels 96, 98 formed in the halfway section of the liquid channel 94, and a reflection part 102 which is formed in the branch channel 98 except at least one of two or more branch channels 96, 98 and reflects a pressure wave generated with the volume change of the pressure chamber 84.
