Abstract
A liquid discharge head includes: a liquid chamber; a supply flow path supplying liquid to the liquid chamber; a discharging flow path being provided away from the supply flow path in a horizontal direction and discharging the liquid from the liquid chamber; a first-connecting-flow-path communicating between the liquid chamber and the supply flow path; and nozzles for discharging the liquid supplied from the liquid chamber. The first-connecting-flow-path includes a first-supply-bottom-surface inclined downward with respect to a horizontal plane at a first-angle from the supply flow path toward the liquid chamber, and a second-supply-bottom-surface located between the first-supply-bottom-surface and the liquid chamber and inclined downward with respect to the horizontal plane at a second-angle from the first-supply-bottom-surface toward the liquid chamber. The first-angle is greater than or equal to 0 degrees and is less than 90 degrees, and the second-angle is greater than the first-angle and is less than 90 degrees.
