<p>Disclosed is a channel constitution member wherein a U-shaped bottom (130b) and a concave eaves (210) are provided as an adhesive holding portion which holds an adhesive material (400) at the lower position of a pipe (201) for upper bend and a pipe (202) for lower bend in the gravity direction, so that the adhesive material (400) stagnates at the bottom (130b) and the concave eaves (210) when the adhesive material (400) is applied in order to reinforce the connection of the pipe (201) for upper bend and the pipe (202) for lower bend with a tube (100), and since the adhesive material (400) can stay, as it is, in the coupling region of a pipe for connection of piping and the tube (100), the adhesive can be cured surely in the coupling region of the pipe for connection of piping and the tube (100) and reliable bonding of the coupling region can be attained. As a result, a channel constitution member and an inkjet head unit, which are adaptable to miniaturization and are capable of reliably preventing the adhesive from entering into the channel without using a fixing member, can be provided.</p> |
