Abstract: A liquid ejection head includes an ejection-port defining member and a substrate having at least three liquid supply openings arranged in an array direction. The substrate has at least one groove in a region between ends of the liquid supply openings and an edge of the substrate. The groove extends from and communicates with the end of at least one of two outermost liquid supply openings of the liquid supply openings in the array direction. The groove extends at least to a position where the groove is superposed on the liquid supply opening next to the liquid supply opening communicating with the groove in an extending direction in which the liquid supply openings extend.

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.

Abstract: A liquid ejection head that includes ejection orifices and is configured by bonding a silicon substrate and a support substrate, flow passages which penetrate a bonding surface between the silicon substrate and the support substrate and through which different types of liquids flow. An in-partition wall space that is open to the bonding surface between the silicon substrate and the support substrate is formed in a partition wall for separating the flow passages. The internal pressure of the in-partition wall space is set to be lower than pressure of the liquid on each of the flow passages.
