Abstract:
Provided are a liquid ejection head and a liquid ejection apparatus which can reduce the distance between an ejection port and a medium as much as possible and can apply liquid to a desired position, even in the case where a member protruding more toward a liquid ejection direction than an ejection port is provided. A liquid ejection apparatus applies liquid to a medium by using a liquid ejection head including an ejection port ejecting the liquid and a member protruding more toward a liquid ejection direction than an ejection port face where the ejection port is formed, wherein a first distance between the ejection port and the medium is smaller than a sum of a second distance from the ejection port face to a tip of the member in the ejection direction and a third distance from the tip to the medium.
