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.

-
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 a gap, between neighboring recording element substrates, on a back surface of an element surface on which the energy generating element is provided is wider than a gap, between the neighboring recording element substrates, on the element surface.
