ABSTRACT:
An ink jet head main body includes an opening provided corresponding to a discharge port, an ink pathway communicated to the opening, and an energy generating member for generating energy to be utilized for discharging ink from the discharge port. The main body is bonded to a discharge port plate, through which the discharge port is located. A method of making the ink jet head includes a bonding step of bonding the member which becomes the discharge port plate to the face of the ink jet head main body where the opening is provided; a pressurizing step of applying pressure to the portion of the discharge port plate which becomes the discharge port; and a discharge port forming step of forming the discharge port on the member which becomes the discharge port plate.
