摘要:
A liquid discharge head includes a channel plate. The channel plate includes a fluid restrictor, a channel, a first plate member, and a second plate member. The channel is disposed on at least one of an upstream side and a downstream side of the fluid restrictor in a direction of flow of liquid. The channel has a greater width than a width of the fluid restrictor in a direction perpendicular to the direction of flow of liquid in an in-plane direction. The first plate member has a through hole including at least one broad portion and a narrow portion. The narrow portion is the fluid restrictor. The second plate member includes at least one through hole constituting part of the channel with the broad portion. The through hole is disposed opposite an end of the narrow portion at which the narrow portion is connected to the broad portion.
