Provided is a liquid ejection head capable of stably ejecting a liquid at a practical liquid droplet velocity without separating minute liquid droplets before ejection of main liquid droplets in the case of reducing the amount of liquid droplets by reducing a nozzle diameter of the liquid ejection head. In a liquid ejection head including a nozzle for ejecting a liquid, a recess portion recessed relative to a nozzle inner wall surface is formed on a nozzle inner wall in a region having a nozzle inner diameter of 15 μm or less.
