Abstract
A liquid jet recording head includes liquid discharge ports, pressure chambers, and a substrate which has the discharge energy generating element, a liquid chamber for storing a liquid supplied to the pressure chamber, a pair of paths which are separated from the liquid chamber, and a liquid supply port communicating with the liquid chamber. A liquid inlet port communicating with one path of the pair of paths and a liquid outlet port communicating with the other path of the pair of paths are opened on one surface of the substrate. A liquid flow path for discharging the liquid from the liquid chamber to the pressure chamber via the liquid supply port, and a liquid flow path for circulating the liquid from the one path to each pressure chamber via the liquid inlet port, and further from each pressure chamber to the other path via the liquid outlet port are provided.
