    摘要： A liquid discharge head that is detachably attached to a recording apparatus includes a liquid discharge substrate, a planar region including a plurality of connection terminals that electrically connect the liquid discharge head to the recording apparatus by sliding relative to the recording apparatus while turning when mounted on the recording apparatus, and definition portions defining a rotational center. The planar region is disposed parallel to the rotational center. Among the plurality of connection terminals, the connection terminal disposed closer to the rotational center is longer in a direction perpendicular to the rotational center and parallel to the planar region than the connection terminal disposed more distant from the rotational center.

    摘要： The present invention provides a liquid ejection head for which the peeling of an orifice plate from a substrate seldom occurs, even in a structure such that the walls that define each energy application chamber are narrowed toward an ejection port. The walls that define a first pressure chamber are inclined inward within the first pressure chamber, so that the first pressure chamber is narrowed, toward an ejection port, along a direction perpendicular to the heater formation face on which heaters are arranged. Further, the walls that define each ink flow path are inclined in the ink ejection direction. Furthermore, the angle at which the walls that define the ink flow path are inclined relative to the ink ejection direction is smaller than the angle at which the walls that define the first pressure chamber are inclined inward, within the first pressure chamber.

    摘要： To provide an inkjet head which includes high-density nozzle rows and which does not easily cause an ejection failure due to adhesion of ink mist around ejection orifices when a high-density image of a secondary color is printed with a small number of paths. An inkjet head includes at least two or more types of nozzle rows that eject different amounts of ink. When A is the cross section, with respect to an ink supplying direction, of an ink supply path from each ejection orifice to a supply port and L is the length of the ink supply path, the value of A/L differs between the two or more types of nozzle rows. The nozzle row of which the value of A/L is small is disposed outside an area between the nozzle rows that eject a largest amount of ink and that are arranged next to each other.
