<p>PROBLEM TO BE SOLVED: To provide a liquid discharge head capable of suppressing deflection of an elastically deformable wall surface member that forms a wall surface of a pressure liquid chamber to prevent occurrence of a bonding failure between the wall surface member and a channel formation member.SOLUTION: A liquid discharge head includes: a nozzle plate 91 having a plurality of nozzles 92; a channel plate 93 having a plurality of individual channels 96 communicating with the nozzles 92; a common liquid chamber 98 for supplying liquid to the plurality of individual channels 96; and a wall surface member 94 having at least a portion of wall surfaces of the individual channels 96. The common liquid chamber 98 is formed at an opposite surface side to a surface side at which the individual channels 96 are formed sandwiching the wall surface member 94. The wall surface member 94 has a deformable damper region 94a that constitutes a portion of the wall surface of the common liquid chamber 98 and a reinforcement region 94c that divides the damper region 94a into a plurality of regions in a nozzle arrangement direction, and in at least a portion of the reinforcement region 94c, has a hollow portion 94b whose thickness is thicker than that of the damper region 94a and thinner than that of the reinforcement region 94c.</p> |
