Abstract
An ink-jet recording head includes a plurality of recording element substrates each having an ejection pressure generating element configured to generate pressure for ejecting ink from an ink discharge port. The plurality of recording element substrates each include a first surface on which the corresponding ejection pressure generating element is disposed and a second surface, serving as an end surface intersecting with the first surface, being at least partially formed by etching.
Claims14
An ink-jet recording head comprising:
- an ink discharge port;
- a plurality of recording element substrates each having an ejection pressure generating element configured to generate pressure for ejecting ink from the ink discharge port, wherein
- the plurality of recording element substrates each include a first surface on which the corresponding ejection pressure generating element is disposed and a second surface, serving as an end surface intersecting with the first surface, being at least partially formed by etching.
A recording element substrate comprising:
- an ink discharge port;
- and
- an ejection pressure generating element configured to generate pressure for ejecting ink from the ink discharge port, wherein
- the recording element substrate includes a first surface on which the ejection pressure generating element is disposed and a second surface that is an end surface intersecting with the first surface, the second surface being at least partially formed by etching.
A method for manufacturing an ink-jet recording head including a recording element substrate formed on a supporting member, the method comprising:
- preparing the recording element substrate, the substrate having an ejection pressure generating element disposed on a main surface of the substrate configured to generate pressure for ejecting ink, a side surface of the main surface being at least partially subjected to etching;
- bringing the etched side surface of the recording element substrate into contact with a positioning portion configured to position the recording element substrate;
- and
- fixing the recording element substrate to the supporting member while the etched side surface of the recording element substrate and the positioning portion are in contact with each other.
A method for manufacturing a recording element substrate having an ejection pressure generating element configured to generate pressure for ejecting ink from an ink discharge port, the method comprising:
- preparing the recording element substrate having the ejection pressure generating element on a first surface of the recording element substrate;
- and
- at least partially applying etching to a second surface serving as an end surface of the recording element substrate intersecting with the first surface.
