PROBLEM TO BE SOLVED: To provide an inkjet head-connecting unit which is reliable without a fear of defective ink ejection and ink leakage. SOLUTION: The inkjet head-connecting unit comprises a face ejection type head member 210 and a case member 240. The head member includes a first face 203 in which nozzles for ejecting ink droplets are formed, and a second face 201 in which an intake port for feeding ink to the nozzles is formed. The case member 240 has an opening 241 for housing the head member therein, and a feeding port 257 formed therein, for feeding the ink to the head member. According to the structure of the inkjet head connecting unit, when the head member is housed in the opening formed in the case member, a space 248 for filling an adhesive is defined between the head member and the case member, and a hole 243 communicating with the space is formed at least one of the head member and the case member.
