The present invention provides an ink jet recording head which, when a smaller liquid droplet is obtained, can 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. In the present invention, two heaters 1a and 1b are provided for each bubble generating chamber and the heaters 1a and 1b 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 out of the second discharge port portion.
