摘要： A liquid ejection head that the adverse effect of a heating resistor element due to cavitation is reduced and a printing apparatus employing this liquid ejection head are provided. When a length of a heating resistor element in a direction in which ink is to be supplied is defined by L, the center of an ejection port is shifted, at a distance of equal to or longer than L/7 toward a location of an ink supply port, from the center of the heating resistor element, viewed in a direction in which ink is to be ejected. When a length of the ejection portion in the direction in which ink is to be ejected is defined as l and a length of a bubble generation chamber in the direction in which the liquid is to be ejected is defined as h, l/h is equal to or smaller than 2.
