PROBLEM TO BE SOLVED: To provide a flow path member which can reserve relatively large air bubbles and can be downsized in a perpendicular direction, and to provide a liquid injection head, and a liquid injection device.SOLUTION: A flow path member includes: a first flow path 310 where liquid flows in a perpendicular direction Z; and a second flow path 320 which intersects with the first flow path 310 where the liquid horizontally flows to intersect with the first flow path 310 in the perpendicular direction. The second flow path 320 includes an air bubble reservoir 321 for the second flow path to reserve air bubbles, and a flow path groove 322 for the second flow path which is provided to communicate with the air bubble reservoir 321 for the second flow path.SELECTED DRAWING: Figure 3 |
