Abstract: A liquid discharge head includes a first component having a bonding face having a recess and a second component bonded to the bonding face of the first component. The recess includes a first recess to which an adhesive is applied and a second recess extending in an extending direction to connect the first recess and an outer peripheral end of the first component. The first recess includes an inner side face that is an interior of the first component. The second recess includes a first wall face and a second wall face opposed to the first wall face. The first wall face and the second wall face define side walls of the second recess in a width direction orthogonal to the extending direction of the second recess. The extending direction is inclined with respect to a perpendicular line perpendicular to the inner side face of the first recess.

Abstract: A liquid discharge head includes: a nozzle plate having multiple nozzles from each of which a liquid is to be discharged, the multiple nozzles arrayed in a longitudinal direction of the nozzle plate; a channel substrate on the nozzle plate in a lamination direction orthogonal to the longitudinal direction, the channel substrate including: multiple channels arrayed in the longitudinal direction in a channel region of the channel substrate, the multiple channels respectively communicating with the multiple nozzles; a first recess outside the channel region in the longitudinal direction; and a flat portion between the channel region and the first recess in the longitudinal direction.
