Abstract
A print element substrate and a liquid ejection head capable of suppressing degradation of a print quality caused by a white stripe/black stripe etc., is actualized without using a high degree of microfabrication technology. As a result of asymmetric deformation by swelling in a direction of relative movement to a print medium, print elements having different liquid droplet ejection directions are made to coexist and arrayed for that purpose.
