Abstract
Without being dependent on design changes, a liquid ejection head and a method of production thereof are provided in which when time-division driving, liquid drop landing deviance in the direction of printing is capable of being corrected. In order to achieve this, before performing an exposure in order to form an ejection port, after forming a cavity that is shifted with respect to the location at which the ejection port is formed, exposure is performed.
