An ink jet recording head can, when a smaller liquid droplet is obtained, suppress or reduce stagnation of liquid in a second discharge port portion, prevent an offset meniscus in a discharge port, reduce unstable satellite(s) and realize stable discharging with less image deterioration and less floating mist. Two heaters are provided for each bubble generating chamber and the heaters are arranged substantially symmetrically with respect to a center or a center of gravity of a second discharge port portion. In a plan view viewed from a direction perpendicular to a main surface of an element substrate, at least one of two heaters is positioned to straddle an inner area of the second discharge port portion and an outer area outside of the second discharge port portion at a region where the bubble generating chamber is communicated with the liquid supply path.
