摘要： In an ink jet recording head from which a small ink droplet and a large ink droplet can be discharged, a common liquid chamber is connected to discharge ports via ink flow paths and pressure chambers, and ink droplets are discharged from the discharge ports by utilizing thermal energy of heaters. Widths of the ink flow paths are narrower than widths of the pressure chambers so that the ink flow paths act as restriction portions. If it is assumed that a sectional area of the small liquid droplet ink flow path is SS, a sectional area of the small liquid droplet pressure chamber is SRS, a sectional area of the large liquid droplet ink flow path is SL and a sectional area of the large liquid droplet pressure chamber is SRL, a relationship SS/SRS
