Abstract
An ink jet recording head is produced by forming in a first substrate a plurality of orifices for ejecting an ink droplet and a reference object for registration; forming in a second substrate ejection energy generating elements for supplying energy for ejecting the ink placed in liquid passages communicating with the orifices; and joining the first substrate and the second substrate together on the basis of the reference object for registration.
