PROBLEM TO BE SOLVED: To increase the flow rate of liquid downstream of a connection part of a supply side individual passage connected to a supply side common passage on the uppermost side in a liquid flow direction. SOLUTION: A part of ink flowing through the supply side common passage 47 flows to a discharge side common passage 53 through a second passage 69. The flow rate of ink thereby increases downstream of the supply side common passage 47 in comparison with the case of the ink not flowing through the second passage 69. The temperature dispersion of ink in the supply side common passage 47 is thereby restrained in comparison with the case of the ink not flowing through the second passage 69, and the temperature variation of ink between ink drop ejection modules 40 is restrained.
