摘要:Problem to be solved: to realize a liquid circulation along the merging passage
and the common channel while suppressing the size of the first direction. Solution 1A
plurality of pressure chambers 20 arranged in the first directionTwo pressure chamber
groups 20A each consisting of 20 x20b andTwo pressure chamber groupsTwo common
channels 31 for each of32 andTwo common channels 31,A first merging path 41 for
connecting one end of the first direction in the first direction ofTwo common channels
31,A second merging path 42 for connecting the other ends of the first and second
directions 32 in the first direction is merging passages 41 and 42 overlap
the pressure chamber 20x in the third direction (the first direction and the direction
perpendicular to both sides of the two pressure chamber groups 20a and 20b).Diagram
