PROBLEM TO BE SOLVED: To enable coexistence of ensuring rigidity of a nozzle sheet and improving the quality of a print. SOLUTION: On the surface of the nozzle sheet 17 in which a nozzle 18 is formed, a recessed part 19 having an opening width larger than an opening width of the nozzle 18 and surrounding the outside of the nozzle 18, is formed. The nozzle 18 is positioned on the bottom face part of the recessed part 19, and by making the inner angle of a corner angle part 19a of the recessed part 19 have an angle larger than 90°(for example, the corner angle part 19a is made to be a curved face or an inclined face), the ink stuck within the recessed part 19 is returned into the nozzle 18 without being torn, so as not to generate a standing of the ink in the recessed part 19.
