Ink solvent having reached a buffer chamber through a manifold and a flexible portion is discharged in a direction different from the direction in which a holder opening is provided. Accordingly, the ink solvent is less likely to reach a connecting portion of a lead electrode and a COF substrate through the holder opening, a through-hole, and a support hole, through which the COF substrate extends. Thus, it is possible to make the solvent take a long time to reach the connecting portion, achieving an ink jet recording head in which the time taken to cause poor contact between the lead electrode and the COF substrate occurs is longer than that in the case where the solvent is discharged in the same direction as the direction in which the holder opening is provided. |
