摘要： The present invention aims at minimizing variations in pressure loss of a liquid supplied to discharge holes. A liquid discharge head 2 of the present invention includes: a plurality of first flow channel members, each having a plurality of discharge holes 8, a plurality of pressurizing chambers 10, a plurality of first common supply flow channels 20, and a plurality of first common recovery flow channels 24, in which the first common supply flow channels 20 and the first common recovery flow channels 24 are long in a first direction D1, and the first flow channel members are disposed in a second direction D2; a second flow channel member 6 having a second common supply flow channel 22 and a second common recovery flow channel 26; and a plurality of pressurizing parts 10 to respectively pressurize the liquid in the pressurizing chambers 10. The second flow channel member 6 is disposed on the first flow channel member 4. The first flow channel member 4 and the second flow channel member 6 are long in the second direction D2. The second common supply flow channel 22 and the second common recovery flow channel 26 are also long in the second direction D2. It is therefore possible to minimize variations in pressure loss that can occur in the pressurizing chambers 10, without increasing the size of the liquid discharge head 2 in a planar direction.
