PURPOSE: A method for manufacturing a fluid injecting device is provided to prevent a damage or breakdown of an injection fluid barrier due to pressure by improving the rigidity of the barrier by performing a curing process on the barrier and then forming an adhesive layer on the barrier. CONSTITUTION: A method for manufacturing a fluid injecting device includes the steps of a forming a driving part(110), forming a membrane(120), and forming a nozzle part(130) having an injection fluid barrier(133) and a nozzle plate(134), wherein the step of forming a nozzle part includes the sub-steps of stacking the nozzle plate on a board and forming a nozzle(132), stacking the injection fluid barrier on the nozzle plate and curing the barrier, forming an adhesive layer(135) on the injection fluid barrier and baking the layer, forming an injection fluid chamber(131) by etching the adhesive layer and the injection fluid barrier, removing the board, and arranging the adhesive layer on the membrane and adhering the layer on the membrane.
