An ink jet recording head includes a liquid discharge head unit having discharge ports and ink flow paths; a liquid container holder unit capable of holding liquid containers and having supply paths for supplying liquid to the liquid discharge head units; and a buffer chamber for allowing gas to exist in the liquid supply paths, the buffer chamber being formed by coupling the liquid discharge head to the liquid supply holder unit. The ink jet recording head enables the buffer chamber allowing to gas to exist to be sufficiently cleaned, and requires no additional process for the formation of the buffer chamber thereof. Furthermore, the ink jet recording head can inhibit ink oscillations in flow paths during ink discharge to keep a stable discharging state, thereby acquiring a high-quality image at all times.
