Abstract
A liquid ejection apparatus includes a liquid supply member having a plurality of liquid supply passages, a connecting surface having a plurality of connecting portions connected to the liquid supply passages, a first positioning portion configured to determine relative positions between the liquid supply passages and the connecting portions in one direction along the connecting surface, and a second positioning portion configured to determine relative positions between the liquid supply passages and the connecting portions in the one direction and an other direction perpendicular to the one direction. A first distance between centers of gravity of the first positioning portion and the connecting portion farthest from the first positioning portion is longer than a second distance between centers of gravity of the second positioning portion and the connecting portion farthest from the second positioning portion.
