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.
