Abstract
A liquid ejection head and liquid ejection apparatus are capable of suppressing deterioration in image quality without adding a member for heat radiation. In the liquid ejection head that ejects a circulating liquid, an engagement part formed on the discharge port side has an elongated hole shape extending in a direction so as to support a liquid ejection unit support member in such a manner as to allow thermal deformation.
