A liquid discharge head includes a nozzle configured to discharge a liquid, a pressure chamber communicating with the nozzle, a pressure generator configured to apply pressure on the pressure chamber, a first substrate including a terminal electrode connected to the pressure generator, and a second substrate including a bonding surface bonded to the first substrate, the second substrate including a terminal opening exposing the terminal electrode of the first substrate. The first substrate includes a through hole penetrating through the first substrate, and the second substrate includes a communication hole communicating with the through hole of the first substrate and an air communication channel on a surface opposite to the bonding surface, the air communication channel communicating with the terminal opening and the communicating hole.
