A head chip unit comprises a first head chip having a first ink chamber configured to contain first ink and having a first channel in communication with the first ink chamber for receiving the first ink from the first ink chamber and via which the first ink is discharged in an ink supply direction of the head chip unit. A second head chip is laminated with the first head chip along a laminating direction generally orthogonal to the ink supply direction. The second head chip has a second ink chamber with an ink supply part configured to receive second ink different from the first ink, a second channel in communication with the second ink chamber for receiving the second ink from the ink supply part and via which the second ink is discharged in the ink supply direction, and an ink supply hole through which the second ink is supplied into the ink supply part of the second ink chamber, the ink supply hole extending in the laminating direction so that the ink supply hole does not overlap the first ink chamber and the first channel of the first head chip. |
