Abstract

An inkjet head unit is provided with an inkjet head (11), which has a head inlet (23a) and a head outlet (23b) on the left and right side surfaces and has the surface covered with a protection film; manifolds (14a, 14b) as channel configuring members; and first and second elastic sealing members (15a, 15b), which are brought into contact with pressure and sandwiched between the inkjet head (11) and the channel configuring members, in a manner of surrounding a channel generated by communication at left and right sections. The outer circumferences of the first and second elastic sealing members (15a, 15b) are surrounded by a sealing agent applied by injection, after the inkjet head (11) and the channel configuring members are arranged to sandwich the first and the second elastic sealing members (15a, 15b).
