Abstract
A liquid discharge head including a substrate, and an energy-generating element. The substrate is provided with a flow path that penetrates through the substrate from the first surface to a second surface, the flow path supplying the liquid from the second surface side to the first surface side. The flow path includes a plurality of first flow paths and a second flow path that is positioned on the second surface side with respect to the first flow paths. The plurality of first flow paths are open on a bottom portion of the second flow path, and the plurality of first flow paths include a long flow path relatively long in a direction perpendicular to the first surface, and a relatively short flow path. The long flow path has a flow path resistance per unit length that is smaller than that of the short flow path.
