Abstract:
By appropriately defining a flow path capacity from an opening of an ink supply path to a nozzle in a pressure chamber, a progress of thickening ink toward the pressure chamber is suppressed. In other words, by setting the individual flow path capacity to be large, specifically, to 4400 pl or higher, desirably 6210 pl or higher, it is possible to suppress the progress of the thickening of the ink even in a small-sized liquid ejecting head of which the shortest formation pitch between each of the nozzles is 1/300 inches. More specifically, a nozzle communication opening is provided between the pressure chamber and the nozzle, and a total capacity of the nozzle communication opening and the pressure chamber is configured to be 4400 pl or higher, desirably 6210 pl or higher.
