Abstract A line ink jet head having a plurality of ink jet head units in a staggered pattern enables the staggered ink jet head units to be easily precisely positioned to each other. The line ink jet head has ink jet head units that are staggered to each other in line with the ink nozzles disposed to the first and second head mounting surfaces on both sides of a head unit mounting layer. If the head unit mounting surface is precisely formed, the ink jet heads can be precisely positioned in staggered rows by simply bonding the ink jet head units to respective mounting surfaces.
