Abstract:
A liquid discharge head including first flow channel members, each having discharge holes, pressurizing chambers, first common supply flow channels, and first common recovery flow channels where the first common supply flow channels and first common recovery flow channels are long in a first direction, and the first flow channel members are disposed in a second direction; a second flow channel member having a second common supply flow channel and a second common recovery flow channel; and pressurizing parts to respectively pressurize the liquid in the pressurizing chambers. The second flow channel member is disposed on the first flow channel member. The first flow channel member, second flow channel member, second common supply flow channel, and second common recovery flow channel are long in the second direction. Pressure loss may therefore be minimized in the pressurizing chambers without increasing the size of the liquid discharge head in a planar direction.
