Abstract
A liquid discharge head includes an actuator substrate including a pressure chamber communicating with a nozzle from which a liquid is to be discharged and a pressure generator to apply pressure to the liquid in the pressure chamber, a frame bonded to the actuator substrate and having a through hole filled with a resin, and a temperature detector inserted into the through hole and attached to the actuator substrate with the resin to detect a temperature of the actuator substrate. The through hole has a first face facing the actuator substrate and a second face opposite to the first face and facing an opening of the frame. The resin in the through hole includes an uncured portion uncured and facing the first face and a cured portion cured and facing the second face. The uncured portion contacts the actuator substrate and is between the cured portion and the actuator substrate.
