There is provided a liquid ejecting head which can introduce a liquid in a liquid storage member to a pressure chamber side via a liquid flow path from a liquid introducing needle and which can eject a liquid in the pressure chamber from a nozzle opening as a liquid drop by operation of a pressure generator. The liquid introducing needle constructed in a hollow needle shape includes an introducing needle portion in which a liquid introducing through hole for introducing a liquid in the liquid storage member is opened, and a cylindrical enlarged diameter straight portion formed at the downstream side of the introducing needle portion and whose inner diameter is enlarged than the inner diameter of the introducing needle portion. The inner space of the enlarged diameter straight portion is to be a bubble chamber which can store a bubble and the enlarged diameter straight portion includes a groove portion extending from the upstream side toward the down stream side on the inner circumference surface. |
