PURPOSE:To make it possible to simply and accurately perform the attachment of ink jet nozzle units with good accuracy by short-time work, by employing constitution provided with the arrangement member for arranging the ink jet nozzle elements with predetermined positional accuracy and a mount part for performing the positional determination and fixation of said arrangement member. CONSTITUTION:An arrangement unit 1 is a box like constitutional body having recessed pars 13, which can perform the positional determination and fixation of ink jet nozzle elements having emitting pressure generation elements 2 attached thereto, integrally formed thereto from plastic with predetermined positional accuracy. An ink sub-tank 4 has a trough shaped mount part 4' capable of receiving and fixing the arrangement unit 11 in front thereof with predetermined accuracy. Therefore, in manufacturing, the ink jet nozzle elements having the emitting pressure generation elements 2 and tubes 3 attached thereto are at first fixed to the arrangement unit 11 in a positionally determined state before the arrangement unit 11 is fixed to the mount part 4' of the ink sub-tank 4 in a positionally determined state. |
