Liquid discharge head and liquid discharge apparatus

A liquid discharge head comprising:

• a nozzle plate including multiple nozzles from which a liquid is dischargeable in a discharge direction, the multiple nozzles arrayed in a nozzle array direction;
• an individual channel member including individual channels respectively communicating with the multiple nozzles;
• multiple pressure generators to generate pressure to discharge the liquid from the multiple nozzles, respectively;
• a wiring member including a drive circuit to output a drive signal to each of the multiple pressure generators;
• a protector adjacent to at least one side of the nozzle plate in a direction perpendicular to the discharge direction and overlapping the drive circuit of the wiring member in the discharge direction;
• a housing holding the protector, the nozzle plate, and the individual channel member, the housing including:
• a gas inlet;
• and
• a gas outlet;
• and
• a gas channel between the protector and the wiring member and communicating with each of the gas inlet and the gas outlet,
• wherein:
• the protector includes a rib facing the wiring member.
