Ink jet head, manufacturing method therefor, and ink jet recording apparatus
An ink jet head in which a multi-nozzle structure is attained, and highly accurate alignment of ink jet head chips is realized, a method for manufacturing the ink jet head, and a recording apparatus on which the ink jet head is mounted. Guide protrusions (141) for alignment of ink jet head chips (41) are formed in an ink jet head chip bonded surface (134) of a nozzle plate (133), the ink jet head chips (41) are aligned by inserting the guide protrusions (141) of the nozzle plate (133) into guide grooves (51) of nozzle surfaces (42) of the ink jet head chips (41), and the nozzle plate (133) and the respective ink jet head chips (41) are bonded with each other by a bonding agent.
