Between the first channel formation member and the second channel formation member, a channel (main channel 9), a buffer chamber 10, and a communication passage 11 are formed. In the second channel formation member, a through hole 12 penetrating the second channel formation member is formed, and a communication port 8 communicating with the through hole 12 is formed at a position facing the inside of the buffer chamber 10. In a use state of the recording head, the communication port 8 is disposed at a position higher than a wall of an upper surface configuring the communication passage 11.
