PROBLEM TO BE SOLVED: To provide a channel constituent member and an inkjet head unit which surely prevent entering of an adhesive into a channel without using a fixation member and also respond to size reduction. SOLUTION: A bottom part 130b of a U-character shape and a concave hood part 210, as an adhesive holding part for making an adhesive material 400 remain, are arranged at a lower position in the gravitational direction of a pipe 201 for an upper vent and a pipe 202 for a lower vent, so that the adhesive material 400 remains in the bottom part 130b and the concave hood part 210 when the adhesive material 400 is coated to reinforce connecting of the pipe 201 for the upper vent and the pipe 202 for the lower vent and a tube 100. Therefore, as the adhesive material 400 can remain, as it is, in a connecting area of pipes for piping connection and the tube 100, an adhesive is surely cured to be able to carry out surely connecting in the connecting area.
