Abstract
There is provided a liquid discharge head comprising a channel-forming body. The channel-forming body includes a nozzle surface in which a plurality of nozzles arranged in a line open. The channel-forming body has formed therein a supply manifold, a return manifold, and a plurality of individual channels. Each individual channel includes a pressure chamber, a descender, a return throttling path, and an interposing channel that interposes between the return throttling path and the descender and communicates with the nozzle. The return throttling path extends in a second direction differing from a first direction in which the interposing channel extends. A cross-sectional area of the return throttling path is smaller than a cross-sectional area of the interposing channel.
