The present invention provides a liquid discharge head in which the possibility of pressure reaching a third flow passage and a fourth flow passage from a discharge unit is reduced. This liquid discharge head 2 comprises: a plurality of discharge units 15 each provided with discharge holes 8, pressurizing chambers 10 in communication with the discharge holes 8, first flow passages 12 for supplying liquid to the pressurizing chambers 10, and second flow passages 14 for recovering liquid from the pressurizing chambers 10; pressurizing sections 50 for pressurizing the pressurizing chambers 10; a third flow passage 20 commonly connected to the first flow passages 12 of each of the plurality of discharge units 15 and supplying liquid to the discharge units 15; a fourth flow passage 24 commonly connected to the second flow passages 24 of each of the plurality of discharge units 15 and recovering liquid from the discharge units 15; and fifth flow passages 17 for connecting the discharge units 15 to each other and having higher flow passage resistance than the first flow passages 12 and the second flow passages 14. |
