LIQUID DISCHARGE HEAD AND LIQUID DISCHARGE HEAD MANUFACTURING METHOD
First Claim
1. A liquid discharge head comprising:
- a plurality of recording element. substrates each having an energy generating element configured to generate energy for discharging liquid from a discharge port; and
a sealing member with which a surround of each of the plurality of recording element, substrates is filled,wherein each of the plurality of recording element substrates includes a recessed portion on an end surface that faces neighboring recording element substrate, and in the recessed portion, a gap between neighboring recording element substrates is wider than a gap between element surfaces on which the energy generating element is provided.

Abstract
A liquid discharge head includes a plurality of recording element substrates each having an energy generating element configured to generate energy for discharging liquid from a discharge port, and a sealing member with which a surround of each of the plurality of recording element substrates is filled. Each of the plurality of recording element substrates includes a recessed portion formed on an end surface facing a neighboring recording element substrate, and in the recessed portion, a gap between neighboring recording element substrates is wider than a gap between element surfaces on which the energy generating element is provided.
