摘要：
A recessed portion is provided on a shorter side of a rectangular liquid supply passage. Thereby a flow pathway by the recessed portion can be ensured, and even in a case where the air bubble is trapped to be closer to and in contact with one end of the liquid supply passage, a difference in flow resistance to two ink flows generated in this state can be made small. In this way, the flow speeds of the inks flowing in the periphery of the air bubble can be made small as a whole, and as a result, it is possible to suppress an ejection failure due to transfer of the air bubble to the ejection opening side or the like.
