Abstract: Provided is a configuration of a liquid ejecting head enabling a stable, continuous ink supply with the off-carriage method, even if force operates in the direction of joint needle insertion and removal. To this end, a joint opening that accepts insertion of a joint needle on a printing apparatus side is placed at a position closer to a joint face between an ejecting head and a sub tank unit than a positioning opening that engages with a positioning member on the printing apparatus side. Consequently, even if external force is produced due to coupling, the force exerted on the joint face that is a weak portion of an inkjet (IJ) head may be minimized.
