Abstract:
A liquid discharge head includes: individual channel rows; a common channel; a supply port via which liquid is supplied to the common channel; and a discharge port via which the liquid is discharged from the common channel. Each of the individual channel rows is formed of individual channels aligned in a first direction, each of the individual channels includes a nozzle, and the individual channel rows are arranged in a second direction crossing the first direction. The common channel extends in the first direction, and extends in the second direction over an entire length of an area in which the individual channel rows are arranged. The common channel overlaps with the individual channel rows in a third direction orthogonal to both of the first and second directions, and communicates with the individual channels constructing each of the individual channel rows.
