A liquid ejection head and a liquid ejection apparatus are capable of efficiently ejecting a liquid having a viscosity of 2.5 cp or above at high frequency. To this end, a relation L≤H−0.4D is satisfied, where D is the thickness of an ejection port plate, H is the distance from an electrothermal conversion element to the outermost surface of the ejection port plate, and L is the height of an air bubble.
