When a high-viscosity ink is used to form a high-speed, high-quality image on plain paper, an insufficient ink supply occurs. A flow path plate (1) is formed from a silicon substrate. The flow path plate (1) has a nozzle communication path (5) communicating with a nozzle (4) serving as an ink flow path having a viscosity of 5 cP or more, a pressurized liquid chamber (6), and an ink supply path. 7 are formed.
