A liquid discharge head includes a discharge port array having discharge ports for discharging liquid, a liquid chamber for supplying liquid to the discharge port array, and a liquid introduction passage for introducing liquid to the liquid chamber. A vertical cross section of the liquid chamber has an elongated shape. The liquid introduction passage is wider than the liquid chamber in a width direction of the elongated shape. A communicating portion is longer than a width of the liquid chamber and shorter than the liquid chamber, and is projecting from the liquid introduction passage for the liquid chamber. A bottom of the liquid introduction passage is disposed at a lower position than a top of the liquid chamber in the communicating portion, and a distance between the top and the bottom is longer than half of the width of the liquid chamber.
