Nozzle plate, liquid discharge head using the same, and recording apparatus

摘要

The nozzle plate 32 of the present disclosure includes a first surface 31a, a second surface 31b that is a surface opposite to the first surface 31a, and a plurality of nozzles 8 that penetrate from the first surface 31a to the second surface 32b. The through-hole 8 has a reverse taper portion whose cross-sectional area increases toward the first surface 31a at least on the first surface 31a side on which the liquid is discharged. 8b, the first surface 31a has a first region and a second region that does not overlap the first region, and the first region has a first through hole, which is the through hole 8. The second through hole, which is the through hole 8, is arranged in the second region, and when the width of the reverse tapered portion 8b when viewed from the first surface 31a side is T, The width T of the reverse tapered portion 8b of the first through hole is equal to the width T of the reverse tapered portion 8b of the second through hole. Large, the thickness in the first region, and wherein the thinner than the thickness in the second region. [Selection] Figure 6
