A liquid discharge head is arranged in a manner that in the cross-section of a discharge port in a liquid discharge direction, the discharge port includes at least one projection that is convex inside the discharge port; a first area, for holding a liquid surface connecting a pillar-shaped liquid that is elongated outside the discharge port; and second areas where a fluid resistance is lower than that in the first area so as to pull the liquid in the discharge port in a direction opposite to the liquid discharge direction. The first area is formed in the direction in which the projection is convex, and the second areas are formed on both sides of the projection.
