Abstract:
A liquid ejecting head comprises a pressure generation chamber communicating with a nozzle opening, a vibrating wall provided as one surface of the pressure generation chamber and vibrates so that ejects the liquid from the nozzle opening, and a resin portion having a recessed arc-shape and formed in a corner of the pressure generation chamber and formed of a resin material having a Young's modulus of less than or equal to 10 GPa. A ratio r/w of a radius r of the surface of the resin portion to a width w of the pressure generation chamber defined by the vibrating wall is greater than or equal to 0.017 and less than or equal to 0.087.
