Abstract
The present invention provides an ink jet recording head that enables stable high-speed continuous printing, its manufacturing method and an ink jet recording device. A bubble generated in a common liquid chamber is moved to the side of an ink tank via a communicating port formed in a sufficient size and a supply passage. That is, a bubble generated inside a common liquid chamber is exhausted satisfactorily from the common liquid chamber by forming the communicating port in a shape which the bubble can pass, resulting in the supply of ink to the common liquid chamber and an individual passage (nozzle) prevented from being blocked by the bubble. As a result, even if high-speed continuous jetting (printing) is performed, stable printing is enabled.
