Abstract
A printing element includes a substrate, an intermediate layer, and a channel forming member layered in this order. The substrate has a common liquid chamber. The channel forming member has a second surface that is a surface facing the substrate via the intermediate layer, and a first surface that is an opposite surface to the second surface. The first surface is formed with a plurality of ejection ports that eject liquid from the common liquid chamber. The second surface is formed with a plurality of channels that allow each of the plurality of ejection ports and the common liquid chamber to communicate with each other, and a plurality of substantially parallel beam structures, the plurality of beam structures forming a slit portion therebetween.
