Abstract
A liquid ejection head includes a plurality of flow paths. The plurality of flow paths includes a first flow path through which a first liquid flows and a second flow path disposed adjacent to the first flow path. A second liquid, having higher average spectral reflectance at a wavelength in a visible light region than the first liquid, flows through the second flow path. When pressure is applied to the first liquid, the pressure applied to the first liquid in the first flow path is lower than pressure applied to the second liquid in the second flow path.
